# Daily Cheer Automaton
## Overview
## The Collective Cheer
> The collective cheering ritual started in Wuhan, China, in January and spread across the globe in the virus's wake. Here, it is sometimes accompanied by the song "New York, New York."
- [What NYC Sounds Like Every Night at 7](https://www.nytimes.com/interactive/2020/04/10/nyregion/nyc-7pm-cheer-thank-you-coronavirus.html)
Sometimes you can't be around at exactly the right time every day to participate in the collective cheer for healthcare workers. This device will remember for you and participate on your behalf, even if you can't. Sometimes we can all use a helping hand.
This project creates an automatic cheering device that will play an MP3 of a crowd cheering every day starting at 7 PM.
We've designed this project around the [Feather system of boards](https://www.adafruit.com/feather), which makes the components modular and easy to put together and expand upon. It can be easily modified to play any MP3 of your choice, and to go off at any time of your choice.
# Daily Cheer Automaton
## Arduino version
There is an Arduino version and CircuitPython version of this project, and they each use different hardware.
The Arduino version uses a Music Maker FeatherWing for MP3 playback and an Adalogger FeatherWing to keep track of the time.

# Daily Cheer Automaton
## Assembly
You'll need a [soldering iron and solder](https://learn.adafruit.com/adafruit-guide-excellent-soldering).
We are building this project around the [FeatherWing Tripler](https://github.com/adafruit/Adafruit_CircuitPython_VS1053/issues/11) to connect the Feather and two FeatherWings.
You could also use [Feather Stacking Headers](https://www.adafruit.com/product/2830) for a different form factor, to have the boards stacked on top of each other rather than next to each other. Decide what you'd like to do, then plan ahead accordingly!
In this example, we'll solder male headers onto the Feather and two FeatherWings, and female headers onto the FeatherWing Tripler.
Follow the instructions for [attaching male headers to your Feather board](https://learn.adafruit.com/adafruit-feather-m0-basic-proto/assembly). It helps to use a [solderless breadboard](https://www.adafruit.com/product/64) to get the headers on straight.
Do the same for the [Music Maker FeatherWing](https://learn.adafruit.com/adafruit-music-maker-featherwing/), attaching **male headers**.
Then attach **male headers** to the [Adalogger FeatherWing](https://learn.adafruit.com/adafruit-adalogger-featherwing/assembly).
Attach **female headers** to the FeatherWing Tripler. You can use one your soldered Feather boards to help keep the female headers straight while you solder.
Place the Feather, Adalogger FeatherWing, and Music Maker FeatherWing into each of the Tripler's slots. The order is up to you, but you may want to consider things which will connect to the device, such as a possible LiPo battery, which would mean placing the Feather on the far right side. Also consider cables that will be connecting to the device, such as a USB cable to the Feather to provide power, or the audio jack output on the Music Maker FeatherWing.
# Daily Cheer Automaton
## Software
## Installing Boards and Libraries
Make sure to use [Arduino IDE 1.6.4 or higher](https://www.arduino.cc/en/Main/Software) and follow [this tutorial](../../../../add-boards-arduino-v164) to install the Adafruit boards.
Download [the code](https://github.com/andydoro/autocheer) from github by clicking **Download ZIP**. Uncompress the file and copy the contents of the **Arduino** folder to your Arduino sketchbook folder.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Daily_Cheer_Automaton/autocheer/autocheer.ino
You will also need to install some Adafruit Arduino libraries. Follow [this tutorial](../../../../adafruit-all-about-arduino-libraries-install-use) if you are unfamiliar with how to do this. You need to install the following Adafruit Arduino libraries:
- [VS1053](https://github.com/adafruit/Adafruit_VS1053_Library) for the Music Maker
- [RTClib](https://github.com/adafruit/RTClib) for the Real Time Clock (RTC)
- [DST\_RTC](https://github.com/andydoro/DST_RTC) for automatic Daylight Saving Time adjustments
All of the libraries should be available through [Arduino's Library Manager](https://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use/library-manager), or you can [install them manually](https://learn.adafruit.com/adafruit-all-about-arduino-libraries-install-use/how-to-install-a-library).
Once you have installed the libraries and have the correct boards installed, choose your board and check if the code compiles. If the libraries aren't installed correctly you will see errors.
## Audio File & SD Card
You'll also need an audio file for the Music Maker to play! We like [this sample of a crowd cheering for front-line medical staff](http://www.orangefreesounds.com/street-crowd-cheering-and-applauding/).
Rename the audio file **cheer.mp3** and make sure your [SD card is FAT32 formatted](https://learn.adafruit.com/adafruit-adalogger-featherwing/using-the-sd-card). Copy the file onto the SD card and insert into the Music Maker FeatherWing.
## Coin Cell
The Adalogger RTC FeatherWing needs a CR1220 coin cell installed in order to work properly and keep time when the device is unpowered.
## Understanding the Code
Conceptually the daily cheering device is simple: the microcontroller is attached to a clock and an MP3 player. Every second, the microcontroller checks the time. If the hour and minute match the appointed time, the microcontroller will have the MP3 player play an MP3.
The selected time is defined in the code here:
```cpp
// the hour and minute you'd like MP3 to start playing
const int PLAYHOUR = 19; // 24 hour time
const int PLAYMIN = 0;
```
The RTC gives time in [24 hour time](https://en.wikipedia.org/wiki/24-hour_clock), so 7 PM is 19:00.
### Daylight Saving Time
Do you live in a territory that observes [daylight saving time](https://en.wikipedia.org/wiki/Daylight_saving_time) (DST)? If you do, you usually have to reprogram your clocks twice a year! This clock includes some code so that the adjustments are made automatically. The code follows [the current rules for DST in the USA](https://en.wikipedia.org/wiki/Daylight_saving_time_in_the_United_States) and Canada. If you live somewhere that follows different DST rules you may be able to modify the code to suit your rules— just look in the [DST\_RTC library functions](https://github.com/andydoro/DST_RTC). Wikipedia has [a great reference on daylight saving time rules](https://en.wikipedia.org/wiki/Daylight_saving_time_by_country).
If you live in a territory that doesn't observe daylight saving time, just alter the following line by changing the `1` to`0`.
```cpp
#define OBSERVE_DST 1
```
The daylight saving time code works by keeping the real time clock on "standard time" and checking to see if the current date falls within daylight saving time. If the date falls within daylight saving time, an hour is added to the displayed time to convert from standard time to daylight saving time.
## Troubleshooting
The serial console will be important for debugging. To see all of the serial output from startup, make sure to uncomment:
```cpp
// Wait for serial port to be opened, remove this line for 'standalone' operation
/*while (!Serial) {
delay(1);
}
*/
```
However, this may prevent the device from working until you open the serial console.
You should see some startup messages, and then the date and time from the RTC being printed every second. Make sure the time is set correctly!
### No audio? MP3 not playing?
You should hear a 1 second tone on startup, to let you know that the Music Maker audio chip (VS1053) is working and able to produce sounds.
Otherwise, check the serial console for error messages. Make sure both the VS1053 and SD card are found. The serial console should indicate both `"VS1053 found"` and `"SD OK!"`. The serial console should also print the contents of the SD card, so you can check that to make sure the SD card is being read correctly.
You can always test that your mp3 will play by using the [VS1053 example sketch](https://learn.adafruit.com/adafruit-music-maker-featherwing/play-music). If you're having trouble, try this [tutorial to make sure your audio file is microcontroller compatible](https://learn.adafruit.com/microcontroller-compatible-audio-file-conversion).

## Assembly
You'll need a [soldering iron and solder](https://learn.adafruit.com/adafruit-guide-excellent-soldering), as well as some wire.

You could also use [Feather Stacking Headers](https://www.adafruit.com/product/2830) for a different form factor, to have the boards stacked on top of each other rather than next to each other. Decide what you'd like to do, then plan ahead accordingly!
In this example, we'll solder male headers onto the Feather M4 Express and FeatherWing, and female headers onto the FeatherWing Doubler.
Follow the instructions for [attaching male headers to your Feather board](https://learn.adafruit.com/adafruit-feather-m0-basic-proto/assembly). It helps to use a [solderless breadboard](https://www.adafruit.com/product/64) to get the headers on straight.
Do the same for the [Adalogger FeatherWing](https://learn.adafruit.com/adafruit-adalogger-featherwing/assembly), attaching **male headers**.
Attach **female headers** to the FeatherWing Doubler. You can use one your soldered feathers to help keep the female headers straight while you solder.
## Headphone Jack
We'll be playing the audio from the Feather M4 Express through this [headphone jack](https://www.adafruit.com/product/1699). We'll solder the headphone jack and some other components to the FeatherWing Doubler, under where the Feather M4 Express will go. The Feather M4 Express should go into the right Feather slot, in case you'd like to attach a LiPo battery.
The headphone jack can fit under the Feather M4. I've moved the Feather M4 to the side so we can see where the headphone jack and other components go.
The middle three pins of the headphone will be connected to **ground**. You can connect them to the Doubler ground rail.
The outer pins of the headphone jack should be connected in series through a 100uF capacitor and a 100 ohm resistor to the Feather M4's A0 and A1 pins. Make sure the cathode sides of the capacitors are connected to the headphone jack. The A0 output (in green) will be the audio left channel and the A1 output (in blue) will be the audio right channel.
Here is a schematic of the circuit. Note that pin 1 of the stereo jack is the middle physical pin. Pins 3 and 4 are the next two inner physical pins. Pins 1, 3, and 4 are all electrically connected to ground. Note that they are **not** connected to pin 2.
# Daily Cheer Automaton
## Software
## Hardware & Software Requirements
We've written software in [CircuitPython for the Feather M4 Express. This tutorial will get you started](https://learn.adafruit.com/adafruit-feather-m4-express-atsamd51/circuitpython). We need to use an M4 (ATSAMD51 32-bit Cortex M4 core) because it's fast enough to play back MP3s. We also need to use CircuitPython version 5.3.0+. [Follow this tutorial to install a newer version of CircuitPython](https://learn.adafruit.com/welcome-to-circuitpython/installing-circuitpython).
## CircuitPython Libraries
The code requires a few libraries, which we need to use with the Adalogger FeatherWing. [Download The latest bundle](https://circuitpython.org/libraries) and install the libraries listed below into the **lib** folder on your Feather M4 Express:
- **adafruit\_bus\_device** folder
- **adafruit\_register** folder
- **adafruit\_pcf8523.mpy**
## CircuitPython Code
Download [the code](https://github.com/andydoro/autocheer) from github by clicking **Download ZIP**. Uncompress the file and copy **code.py** from the **CircuitPython** folder to your Feather M4 Express **CIRCUITPY** drive.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/Daily_Cheer_Automaton/CircuitPython/code.py
## Audio File & SD Card
You'll also need an audio file for the Feather M4 to play! We like [this sample of a crowd cheering for front-line medical staff](http://www.orangefreesounds.com/street-crowd-cheering-and-applauding/).
The Feather M4 doesn't have enough storage space for this audio file, so we'll need to use an SD card. Rename the audio file "cheer.mp3" and make sure your [SD card is FAT32 formatted](https://learn.adafruit.com/adafruit-adalogger-featherwing/using-the-sd-card). Copy the file onto the SD card and insert it into the Adalogger FeatherWing.
## Coin Cell
The Adalogger RTC FeatherWing needs a CR1220 coin cell installed in order to work properly and keep time when the device is unpowered.
## Understanding the Code
Conceptually, the daily cheering device is simple: the Feather M4 Express is attached to a clock. Every second, the Feather M4 Express checks the time. If the hour and minute match the appointed time, the Feather M4 Express will play an MP3 off the SD card.
The selected time is defined in the code here:
```python
# selected time
# 24 hour time
playhour = 19
playmin = 0
```
The RTC uses [24 hour time](https://en.wikipedia.org/wiki/24-hour_clock), so 7 PM is 19:00.
### Serial Monitor
You can use [Mu Editor](https://learn.adafruit.com/welcome-to-circuitpython/installing-mu-editor) or another program to examine the serial output from the Feather M4.
### SD Card & Audio File
On startup, the program will [mount the SD card and print its contents](https://learn.adafruit.com/adafruit-adalogger-featherwing/using-the-sd-card). This is a good way to troubleshoot the SD card.
It will find the specified audio file and set the file to play stereo audio on the A0 and A1 pins.
```python
data = open("/sd/cheer.mp3", "rb")
mp3 = audiomp3.MP3Decoder(data)
#a = audioio.AudioOut(board.A0) # mono
a = audioio.AudioOut(board.A0, right_channel=board.A1) # stereo sound through A0 & A1
```
### RTC (Real Time Clock) & Setting The Time
Afterwards, you should see the date and time being printed every second.
```python
# Main loop:
while True:
t = rtc.datetime
# print(t) # uncomment for debugging
print(
"The date is {} {}/{}/{}".format(
days[int(t.tm_wday)], t.tm_mday, t.tm_mon, t.tm_year
)
)
print("The time is {}:{:02}:{:02}".format(t.tm_hour, t.tm_min, t.tm_sec))
```
If the time is incorrect, you can set it in the following section of code by changing `False` to `True`:
```python
if False: # change to True if you want to set the time!
# year, mon, date, hour, min, sec, wday, yday, isdst
t = time.struct_time((2020, 5, 13, 15, 15, 15, 0, -1, -1))
# you must set year, mon, date, hour, min, sec and weekday
# yearday is not supported, isdst can be set but we don't do anything with it at this time
print("Setting time to:", t) # uncomment for debugging
rtc.datetime = t
print()
```
This will change the time on the Adalogger FeatherWing's RTC. The RTC runs off the CR1220 coin cell battery when it isn't attached to power, which is how it continues to keep track of the time when the Feather is unpowered. Set `True` back to `False` once the time is set correctly. You can read more about the [RTC and setting the time in the Adalogger FeatherWing Learn Guide](https://learn.adafruit.com/adafruit-adalogger-featherwing/rtc-with-circuitpython).
