# PyPortal Wake-Up Light Alarm Clock
## Overview
Do you suffer from a lack of natural sunlight in your room? Does the lack of sunlight make it almost impossible to get out of bed when you hear a dreadful alarm?
Yes, windows would be nice, but we live in New York City and who needs those when you got a PyPortal and a NeoPixel strip?
In this project, you can wake up to a soft white light fading into your consciousness! [You could get a consumer grade sunrise alarm clock](https://www.cnet.com/how-to/light-alarm-clock-wake-up-to-light/) that may solve your problem but you can also do it yourself!
Using a PyPortal, and a NeoPixel strip, make a sunrise alarm clock that wakes you up with light! Program the PyPortal with CircuitPython to set your wake-up times and the strip will begin to brighten 30 minutes before your wake-up time.
## Prerequisite guides
This project may require some soldering depending on the NeoPixel strip you get. Here's a great guide on soldering if it's your first time or you need some refreshing!

# PyPortal Wake-Up Light Alarm Clock
## Connect Electronics
First we'll connect the electronics before we add the code and attach the strip to a bed frame (or another piece of furniture).
Because [these specific NeoPixel strips](https://www.adafruit.com/product/2832?length=1) come in 5 meter reels, if you order 1m of reel you may get a piece of reel in the middle and thus may have to solder to the pads of the strip. Here are the two possibilities of strip end you may get and how to connect to the PyPortal with each.
## Connect without soldering
If the **data in** end of your neopixel strip looks like this, connect wires the following way.
Info:
- Attach the JST connector to **D3** on the back of the PyPortal.
- Plug the white and black cables into the corresponding inputs on the NeoPixel strip.
- Connect the alligator clips from the red JST cable to the red NeoPixel cable.
## Connect by soldering:
[Here's a great guide to soldering](https://learn.adafruit.com/adafruit-guide-excellent-soldering/tools) for your reference.
If the **data in** end of your NeoPixel strip looks like this, connect wires the following way.
- Prep 3 wires, preferable a red, black and white.
- Solder red to **5V** , white to **Din** and black to **GND** on the neopixel strip.
- Attach the JST connector to **D3** on the back of the PyPortal.
- Connect the female breadboard cables from the PyPortal to the NeoPixel strip.

## Install CircuitPython
[CircuitPython](https://github.com/adafruit/circuitpython) is a derivative of [MicroPython](https://micropython.org) designed to simplify experimentation and education on low-cost microcontrollers. It makes it easier than ever to get prototyping by requiring no upfront desktop software downloads. Simply copy and edit files on the **CIRCUITPY** "flash" drive to iterate.
The following instructions will show you how to install CircuitPython. If you've already installed CircuitPython but are looking to update it or reinstall it, the same steps work for that as well!
## Set up CircuitPython Quick Start!
Follow this quick step-by-step for super-fast Python power :)
[Download the latest version of CircuitPython for the PyPortal via CircuitPython.org](https://circuitpython.org/board/pyportal/)
[Download the latest version of CircuitPython for the PyPortal Pynt via CircuitPython.org](https://circuitpython.org/board/pyportal_pynt/)
**Click the link above to download the latest version of CircuitPython for the PyPortal.**
Download and save it to your desktop (or wherever is handy).
Plug your PyPortal into your computer using a known-good USB cable.
**A lot of people end up using charge-only USB cables and it is very frustrating! So make sure you have a USB cable you know is good for data sync.**
Double-click the **Reset** button on the top in the middle (magenta arrow) on your board, and you will see the NeoPixel RGB LED (green arrow) turn green. If it turns red, check the USB cable, try another USB port, etc. **Note:** The little red LED next to the USB connector will pulse red. That's ok!
If double-clicking doesn't work the first time, try again. Sometimes it can take a few tries to get the rhythm right!
You will see a new disk drive appear called **PORTALBOOT**.
Drag the **adafruit-circuitpython-pyportal-\.uf2** file to **PORTALBOOT.**
The LED will flash. Then, the **PORTALBOOT** drive will disappear and a new disk drive called **CIRCUITPY** will appear.
If you haven't added any code to your board, the only file that will be present is **boot\_out.txt**. This is absolutely normal! It's time for you to add your **code.py** and get started!
That's it, you're done! :)

# PyPortal Wake-Up Light Alarm Clock
## PyPortal CircuitPython Setup
To use all the amazing features of your PyPortal with CircuitPython, you must first install a number of libraries. This page covers that process.
# Adafruit CircuitPython Bundle
Download the Adafruit CircuitPython Library Bundle. You can find the latest release here:
[Latest Adafruit CircuitPython Library Bundle](https://circuitpython.org/libraries)
Download the **adafruit-circuitpython-bundle-\*.x-mpy-\*.zip** bundle zip file where **\*.x MATCHES THE VERSION OF CIRCUITPYTHON YOU INSTALLED** , and unzip a folder of the same name. Inside you'll find a **lib** folder. You have two options:
- You can add the **lib** folder to your **CIRCUITPY** drive. This will ensure you have _all the drivers_. But it will take a bunch of space on the 8 MB disk
- Add each library as you need it, this will reduce the space usage but you'll need to put in a little more effort.
At a minimum we recommend the following libraries, in fact we more than recommend. They're basically required. So grab them and install them into **CIRCUITPY/lib** now!
- **adafruit\_esp32spi** - This is the library that gives you internet access via the ESP32 using (you guessed it!) SPI transport. You need this for anything Internet
- **adafruit\_requests** - This library allows us to perform HTTP requests and get responses back from servers. GET/POST/PUT/PATCH - they're all in here!
- adafruit\_connection\_manager - used by adafruit\_requests.
- **adafruit\_pyportal** - This is our friendly wrapper library that does a lot of our projects, displays graphics and text, fetches data from the internet. Nearly all of our projects depend on it!
- **adafruit\_portalbase** - This library is the base library that adafruit\_pyportal library is built on top of.
- **adafruit\_touchscreen** - a library for reading touches from the resistive touchscreen. Handles all the analog noodling, rotation and calibration for you.
- **adafruit\_io** - this library helps connect the PyPortal to our free datalogging and viewing service
- **adafruit\_imageload** - an image display helper, required for any graphics!
- **adafruit\_display\_text** - not surprisingly, it displays text on the screen
- **adafruit\_bitmap\_font** - we have fancy font support, and its easy to make new fonts. This library reads and parses font files.
- **adafruit\_slideshow** - for making image slideshows - handy for quick display of graphics and sound
- **neopixel** - for controlling the onboard neopixel
- **adafruit\_adt7410** - library to read the temperature from the on-board Analog Devices ADT7410 precision temperature sensor (not necessary for Titano or Pynt)
- **adafruit\_bus\_device** - low level support for I2C/SPI
- **adafruit\_fakerequests** - This library allows you to create fake HTTP requests by using local files.
# PyPortal Wake-Up Light Alarm Clock
## Create Your settings.toml File
CircuitPython works with WiFi-capable boards to enable you to make projects that have network connectivity. This means working with various passwords and API keys. As of [CircuitPython 8](https://circuitpython.org/downloads), there is support for a **settings.toml** file. This is a file that is stored on your **CIRCUITPY** drive, that contains all of your secret network information, such as your SSID, SSID password and any API keys for IoT services. It is designed to separate your sensitive information from your **code.py** file so you are able to share your code without sharing your credentials.
CircuitPython previously used a **secrets.py** file for this purpose. The **settings.toml** file is quite similar.
Warning: Your **settings.toml** file should be stored in the main directory of your **CIRCUITPY** drive. It should not be in a folder.
## CircuitPython **settings.toml** File
This section will provide a couple of examples of what your **settings.toml** file should look like, specifically for CircuitPython WiFi projects in general.
The most minimal **settings.toml** file must contain your WiFi SSID and password, as that is the minimum required to connect to WiFi. Copy this example, paste it into your **settings.toml** , and update:
- `your_wifi_ssid`
- `your_wifi_password`
```auto
CIRCUITPY_WIFI_SSID = "your_wifi_ssid"
CIRCUITPY_WIFI_PASSWORD = "your_wifi_password"
```
Many CircuitPython network-connected projects on the Adafruit Learn System involve using Adafruit IO. For these projects, you must _also_ include your Adafruit IO username and key. Copy the following example, paste it into your settings.toml file, and update:
- `your_wifi_ssid`
- `your_wifi_password`
- `your_aio_username`
- `your_aio_key`
```auto
CIRCUITPY_WIFI_SSID = "your_wifi_ssid"
CIRCUITPY_WIFI_PASSWORD = "your_wifi_password"
ADAFRUIT_AIO_USERNAME = "your_aio_username"
ADAFRUIT_AIO_KEY = "your_aio_key"
```
Some projects use different variable names for the entries in the **settings.toml** file. For example, a project might use `ADAFRUIT_AIO_ID` in the place of `ADAFRUIT_AIO_USERNAME`. **If you run into connectivity issues, one of the first things to check is that the names in the settings.toml file match the names in the code.**
Warning: Not every project uses the same variable name for each entry in the **settings.toml** file! Always verify it matches the code.
## **settings.toml** File Tips
Here is an example **settings.toml** file.
```auto
# Comments are supported
CIRCUITPY_WIFI_SSID = "guest wifi"
CIRCUITPY_WIFI_PASSWORD = "guessable"
CIRCUITPY_WEB_API_PORT = 80
CIRCUITPY_WEB_API_PASSWORD = "passw0rd"
test_variable = "this is a test"
thumbs_up = "\U0001f44d"
```
In a **settings.toml** file, it's important to keep these factors in mind:
- Strings are wrapped in double quotes; ex: `"your-string-here"`
- Integers are _ **not** _ quoted and may be written in decimal with optional sign (`+1`, `-1`, `1000`) or hexadecimal (`0xabcd`).
- Floats (decimal numbers), octal (`0o567`) and binary (`0b11011`) are not supported.
- Use `\u` escapes for weird characters, `\x` and `\ooo` escapes are not available in **.toml** files
- Example: `\U0001f44d` for 👍 (thumbs up emoji) and `\u20ac` for € (EUR sign)
- Unicode emoji, and non-ASCII characters, stand for themselves as long as you're careful to save in "UTF-8 without BOM" format
When your **settings.toml ** file is ready, you can save it in your text editor with the **.toml** extension.
## Accessing Your **settings.toml** Information in **code.py**
In your **code.py** file, you'll need to `import` the `os` library to access the **settings.toml** file. Your settings are accessed with the `os.getenv()` function. You'll pass your settings entry to the function to import it into the **code.py** file.
```python
import os
print(os.getenv("test_variable"))
```
In the upcoming CircuitPython WiFi examples, you'll see how the **settings.toml ** file is used for connecting to your SSID and accessing your API keys.
# PyPortal Wake-Up Light Alarm Clock
## Internet Connect!
# Connect to WiFi
OK, now that you have your **settings.toml** file set up - you can connect to the Internet.
To do this, you need to first install a few libraries, into the lib folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script.
Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, open the directory **examples/** and then click on the directory that matches the version of CircuitPython you're using and copy the contents of that directory to your **CIRCUITPY** drive.
Your **CIRCUITPY** drive should now look similar to the following image:
Info: Update to CircuitPython 9.2.x or later to use this example.
https://github.com/adafruit/Adafruit_CircuitPython_ESP32SPI/blob/main/examples/esp32spi_simpletest.py
And save it to your board, with the name **code.py**.
Don't forget you'll also need to create the **settings.toml** file as seen above, with your WiFi ssid and password.
In a serial console, you should see something like the following. For more information about connecting with a serial console, view the guide [Connecting to the Serial Console](https://learn.adafruit.com/welcome-to-circuitpython/kattni-connecting-to-the-serial-console).
```terminal

----------------------------------------
Done!
```
Going over the example above, here's a breakdown of what the program is doing:
- Initialize the ESP32 over SPI using the SPI port and 3 control pins:
```python
esp32_cs = DigitalInOut(board.ESP_CS)
esp32_ready = DigitalInOut(board.ESP_BUSY)
esp32_reset = DigitalInOut(board.ESP_RESET)
#...
else:
spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)
```
- Get the socket pool and the SSL context, and then tell the `adafruit_requests` library about them.
```python
pool = adafruit_connection_manager.get_radio_socketpool(esp)
ssl_context = adafruit_connection_manager.get_radio_ssl_context(esp)
requests = adafruit_requests.Session(pool, ssl_context)
```
- Verify an ESP32 is found, checks the firmware and MAC address
```auto
if esp.status == adafruit_esp32spi.WL_IDLE_STATUS:
print("ESP32 found and in idle mode")
print("Firmware vers.", esp.firmware_version)
print("MAC addr:", ":".join("%02X" % byte for byte in esp.MAC_address))
```
- Perform a scan of all access points it can see and print out the name and signal strength.
```python
for ap in esp.scan_networks():
print("\t%-23s RSSI: %d" % (ap.ssid, ap.rssi))
```
- Connect to the AP we've defined here, then print out the local IP address. Then attempt to do a domain name lookup and ping google.com to check network connectivity. (Note sometimes the ping fails or takes a while; this isn't a big deal.)
```python
print("Connecting to AP...")
while not esp.is_connected:
try:
esp.connect_AP(ssid, password)
except OSError as e:
print("could not connect to AP, retrying: ", e)
continue
print("Connected to", esp.ap_info.ssid, "\tRSSI:", esp.ap_info.rssi)
print("My IP address is", esp.ipv4_address)
print(
"IP lookup adafruit.com: %s" % esp.pretty_ip(esp.get_host_by_name("adafruit.com"))
)
```
Now we're getting to the really interesting part of the example program. We've written a library for web fetching web data, named [adafruit\_requests](https://github.com/adafruit/Adafruit_CircuitPython_Requests). It is a lot like the regular Python library named [requests](https://requests.readthedocs.io/en/latest/). This library allows you to send HTTP and HTTPS requests easily and provides helpful methods for parsing the response from the server.
- Here is the part of the example program is fetching text data from a URL.
```python
TEXT_URL = "http://wifitest.adafruit.com/testwifi/index.html" # Further up in the program
# ...
print("Fetching text from", TEXT_URL)
r = requests.get(TEXT_URL)
print('-' * 40)
print(r.text)
print('-' * 40)
r.close()
```
- Finally, here the program is fetching some JSON data. The `adafruit_requests` library will parse the JSON into a Python dictionary whose structure is the same as the structure of the JSON.
```auto
JSON_URL = "http://wifitest.adafruit.com/testwifi/sample.json" # Further up in the program
# ...
print("Fetching json from", JSON_URL)
r = requests.get(JSON_URL)
print('-' * 40)
print(r.json())
print('-' * 40)
r.close()
```
# Advanced Requests Usage
Want to send custom HTTP headers, parse the response as raw bytes, or handle a response's http status code in your CircuitPython code?
We've written an example to show advanced usage of the requests module below.
To use with CircuitPython, you need to first install a few libraries, into the lib folder on your **CIRCUITPY** drive. Then you need to update **code.py** with the example script.
Thankfully, we can do this in one go. In the example below, click the **Download Project Bundle** button below to download the necessary libraries and the **code.py** file in a zip file. Extract the contents of the zip file, open the directory **examples/** and then click on the directory that matches the version of CircuitPython you're using and copy the contents of that directory to your **CIRCUITPY** drive.
https://github.com/adafruit/Adafruit_CircuitPython_Requests/blob/main/examples/esp32spi/requests_esp32spi_advanced.py
Your **CIRCUITPY** drive should now look similar to the following image:
# WiFi Manager
The way the examples above connect to WiFi works but it's a little finicky. Since WiFi is not necessarily so reliable, you may have disconnects and need to reconnect. For more advanced uses, we recommend using the `WiFiManager` class. It will wrap the connection/status/requests loop for you - reconnecting if WiFi drops, resetting the ESP32 if it gets into a bad state, etc.
Here's a more advanced example that shows using the `WiFiManager` and also how to fetch the current time from a web source.

# PyPortal Wake-Up Light Alarm Clock
## Using the Wake-Up Light
## Here's an example of the wake-up light in use (for a late riser...)
First enter in the time you want to wake up each day of the week and save the **code.py** file.
```
# type in time to get up each day of the week
default_wake_up = "12:10P"
up_time_monday = default_wake_up
up_time_tuesday = default_wake_up
up_time_wednesday = default_wake_up
up_time_thursday = default_wake_up
up_time_friday = default_wake_up
up_time_saturday = "1:00P"
up_time_sunday = "1:00P"
```
That's it! The program does the rest of the work for you!
## Before wake-up time
Current Time: 11:39AM
Wake-up time: 12:10PM
Light starting at 11:40AM
If the current time is before the "light on" time, the display's backlight should be off unless activated by touch, in which case the backlight comes on for 5 seconds then turns back off.
## During wake-up time
Current Time: 11:40AM
Wake-up time: 12:10PM
Light starting at 11:40AM
If the current time = the "light on" time, the strip will turn on and get brighter every minute for 30 minutes until the wake-up time is reached.
## After wake-up time
Current Time: 12:11PM
Wake-up time: 12:10PM
Light starting at 11:40AM
After the wake-up time is reached, tap the screen to turn off the strip and the next day's wake-up time will be displayed on the screen.
## How it works
The wake-up light does quite a few tricks to deliver light at your wake-up time.
## Displaying text
When the backlight is on, we see the current time, wake-up time and light-starting time displayed on the screen.
The fonts, color and locations of these text elements are initialized at the beginning of the program.
```auto
# assign fonts
big_font = bitmap_font.load_font(cwd+"/fonts/Nunito-Light-75.bdf")
big_font.load_glyphs(b'0123456789:AP') # pre-load glyphs for fast printing

## Text position
The PyPortal's display is 320 pixels wide and 240 pixels high. In order to refer to those positions on the screen, we use an x/y coordinate system, where x is horizontal and y is vertical.
The origin of this coordinate system is the upper left corner. This means that a pixel placed at the upper left corner would be (0,0) and the lower right corner would be (320, 240).
## Font
The fonts used here are bitmap fonts made from the Nunito typeface. You can learn more about [converting type in this guide](https://learn.adafruit.com/custom-fonts-for-pyportal-circuitpython-display).
## Text color
Customize your wake-up light by changing the text colors! You will need to use the hexidecimal value for any color you want to display.
You can use something like [https://htmlcolorcodes.com/](https://htmlcolorcodes.com/) to pick your color and then copy the hex value.
## Initializing wake-up times
This part of the program converts all the user-entered wake up times into time "objects" that can be easily manipulated later to add / subtract minutes, hours and days to the times!
```
# parse given time string into hour minute and AM_PM elements
def parseTime(time_before):
hours_before, minutes_before = time_before.split(":")
AM_PM_str = minutes_before[-1:]
minutes_before = int(minutes_before[:-1])
if (hours_before != '12') and AM_PM_str == 'P':
hours_before = int(hours_before) + 12
elif ((hours_before == '12') and (AM_PM_str == 'P')):
hours_before = int(hours_before)
elif ((hours_before == '12') and (AM_PM_str == 'A')):
hours_before = 0
else:
hours_before = int(hours_before)
parsed_time = [hours_before, minutes_before]
return parsed_time
# get time objects for wake up times
val_times = []
parsed_times = []
for i in range(len(wake_up_times)):
parsed_time_day = parseTime(wake_up_times[i])
hours, minutes = parsed_time_day[0:2]
now_day = time.localtime()
time_obj_mk = time.mktime((now_day[0], now_day[1], now_day[2], hours,
minutes, now_day[5], i, now_day[7], now_day[8]))
time_obj = time.localtime(time_obj_mk)
val_times.append(time_obj_mk)
parsed_times.append(time_obj)
```
## Main loop
`while True:`
In the **repeating** main loop, the following actions are performed:
1. Declare a variable to reference local time.
2. Query local time on first run and once an hour after.
3. Display current time to screen.
4. Determine which wake-up time to choose based on the current day.
5. Turn on/off backlight depending on time.
6. Get the time that is 30 min before the chosen wake-up time.
7. If current day is same as wake-up day and wake-up time - 30 minutes equals current time, start the strip light.
8. Increase brightness of light once a min for 30 min until light has reached maximum brightness. Also update the time.
9. After wake-up time is reached, if user taps screen, turn off strip light.
10. Delay for 1 second.
```
while True:
time_now = time.localtime()
# only query the online time once per hour (and on first run)
if (not refresh_time) or (time.monotonic() - refresh_time) > 3600:
try:
print("Getting time from internet!")
pyportal.get_local_time()
refresh_time = time.monotonic()
except RuntimeError as e:
print("Some error occured, retrying! -", e)
continue
time_str_text = displayTime()
print(time_str_text)
# determine which wake up time to choose based on the day
wake_up_day = whichDay()
# if time is more than 9 hours after previous day's wake up time,
# backlight off and can tap to turn on
backLight()
# start the light 30 min before wake up time
start_light_time = subtract30min(wake_up_day)
# If current day is same as wake up day and
# wake up time - 30 minutes equals current time, start the light
if wake_up_day == time_now[6] and time_str_text == start_light_time:
print("Starting wake up light")
# turn on backlight
pyportal.set_backlight(backlight_on)
for i in range(light_minutes - 1):
BRIGHTNESS = BRIGHTNESS + (MAX_BRIGHTNESS/light_minutes) # max 0.25, min 0.0
strip.fill(WHITE)
strip.brightness = BRIGHTNESS
displayTime()
time.sleep(60) # 60 for once per min
while not pyportal.touchscreen.touch_point: # turn strip off
displayTime()
time.sleep(1)
continue
strip.brightness = MIN_BRIGHTNESS
# update every second so that screen can be tapped to view time
time.sleep(1)
```
# PyPortal Wake-Up Light Alarm Clock
## Affixing the Strip
## Attaching strip to bed frame or other furniture
- Cut 5 or more pieces of double sided foam tape.
- Take off one side of a piece, add some hot glue to it and stick to the NeoPixel strip on one end.
- Repeat with the rest of the pieces trying to make each piece equidistant to the next.
- Reinforce pieces with extra hot glue if desired.
- Now take the other sides of the foam pieces off exposing the sticky sides.
- Carefully place behind bed frame or another convenient bedroom object.
- Attach alligator clips the the ends of the strip to lengthen reach to PyPortal on a night stand.
- Use a piece of tape to hold alligator clips in place.
- Connect clips to JST wires on PyPortal.
All done, now go to bed! And get ready to be waken up by _light..._
## Adding features
Want to take this light to the next level? What features can you add to make it even better?
Some initial ideas:
- Setting the wake-up time using the touch screen.
- Ability to change the color of light you wake up to.
- Ability to change between 12 hour and 24 hour time.
- Add some fun sounds to wake up to once the light has reached full brightness!
