# LED Rocket Lamp
## Overview
https://youtu.be/y2R32idF38I
You can build a SciFi inspired Rocket Lamp with electronics from Adafruit, coded with CircuitPython.
This features NeoPixel LEDs and a speaker to create a rocket-themed white noise generator.
At the base, it’s got an LED toggle switch for powering on the device.
A Stemma QT rotary encoder features two modes for adjusting the brightness of the LEDs and volume of the sound effects.
We think it’s a great project for young makers to inspire them while they’re awake and help soothe them to sleep.
## Feather RP 2040 + Prop-Maker
Powered by the Adafruit Feather RP2040 and the Prop-Maker FeatherWing, these two boards are the perfect match for making advanced props with LEDs and sound effects!
This is a great basis for toys or props that require LEDs, sounds, motion sensing, even 3W LEDs, or in this case a fan!
It features a mini fan, speaker, NeoPixels, LED toggle switch and a Stemma QT rotary encoder.
## Magnetic USB plug
This USB cable features magnetic tips and provides the lamp with 5V of USB power.
This cable makes managing lots of dev boards or gadgets super easy.
The removable magnetic end that lets you quickly connect or disconnect with magnetic alignment. It's like having a 'MagSafe' connector for everything. Works with any and all devices, for both data-sync and power, for 5V up to 2A.

## Circuit Diagram
The wiring diagram below provides a visual reference for connecting the components. It is not true to scale, it is just meant to be used as reference. This diagram was created using the [Fritzing software package](http://fritzing.org/download/).
Take a moment to review the components in the circuit diagram. This illustration is meant for referencing wired connections - the length of wire, position and size of components are not exact.
# LED Rocket Lamp
## 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** drive to iterate.
## CircuitPython Quickstart
Follow this step-by-step to quickly get CircuitPython running on your board.
[Download the latest version of CircuitPython for this board via circuitpython.org](https://circuitpython.org/board/adafruit_feather_rp2040/)
**Click the link above to download the latest CircuitPython UF2 file.**
Save it wherever is convenient for you.
To enter the bootloader, hold down the **BOOT/**** BOOTSEL button**(highlighted in red above), and while continuing to hold it (don't let go!), press and release the**reset button**(highlighted in red or blue above). **Continue to hold the BOOT/BOOTSEL button until the RPI-RP2 drive appears!**
If the drive does not appear, release all the buttons, and then repeat the process above.
You can also start with your board unplugged from USB, press and hold the BOOTSEL button (highlighted in red above), continue to hold it while plugging it into USB, and wait for the drive to appear before releasing the button.
A lot of people end up using charge-only USB cables and it is very frustrating! **Make sure you have a USB cable you know is good for data sync.**
You will see a new disk drive appear called **RPI-RP2**.
Drag the **adafruit\_circuitpython\_etc.uf2** file to **RPI-RP2.**
The **RPI-RP2** drive will disappear and a new disk drive called **CIRCUITPY** will appear.
That's it, you're done! :)
## Safe Mode
You want to edit your **code.py** or modify the files on your **CIRCUITPY** drive, but find that you can't. Perhaps your board has gotten into a state where **CIRCUITPY** is read-only. You may have turned off the **CIRCUITPY** drive altogether. Whatever the reason, safe mode can help.
Safe mode in CircuitPython does not run any user code on startup, and disables auto-reload. This means a few things. First, safe mode _bypasses any code in_ **boot.py** (where you can set **CIRCUITPY** read-only or turn it off completely). Second, _it does not run the code in_ **code.py**. And finally, _it does not automatically soft-reload when data is written to the_ **CIRCUITPY** _drive_.
Therefore, whatever you may have done to put your board in a non-interactive state, safe mode gives you the opportunity to correct it without losing all of the data on the **CIRCUITPY** drive.
### Entering Safe Mode
To enter safe mode when using CircuitPython, plug in your board or hit reset (highlighted in red above). Immediately after the board starts up or resets, it waits 1000ms. On some boards, the onboard status LED (highlighted in green above) will blink yellow during that time. If you press reset during that 1000ms, the board will start up in safe mode. It can be difficult to react to the yellow LED, so you may want to think of it simply as a slow double click of the reset button. (Remember, a fast double click of reset enters the bootloader.)
### In Safe Mode
If you successfully enter safe mode on CircuitPython, the LED will intermittently blink yellow three times.
If you connect to the serial console, you'll find the following message.
```terminal
Auto-reload is off.
Running in safe mode! Not running saved code.
CircuitPython is in safe mode because you pressed the reset button during boot. Press again to exit safe mode.
Press any key to enter the REPL. Use CTRL-D to reload.
```
You can now edit the contents of the **CIRCUITPY** drive. Remember, _your code will not run until you press the reset button, or unplug and plug in your board, to get out of safe mode._
## Flash Resetting UF2
If your board ever gets into a really _weird_ state and CIRCUITPY doesn't show up as a disk drive after installing CircuitPython, try loading this 'nuke' UF2 to RPI-RP2. which will do a 'deep clean' on your Flash Memory. **You will lose all the files on the board** , but at least you'll be able to revive it! After loading this UF2, follow the steps above to re-install CircuitPython.

# LED Rocket Lamp
## Coding the LED Rocket Lamp
Once you've finished setting up your Feather RP2040 with CircuitPython, you can access the code and necessary libraries by downloading the Project Bundle.
To do this, click on the ** Download Project Bundle** button in the window below. It will download to your computer as a zipped folder.
https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/main/White_Noise_Rocket/code.py
## Upload the Code and Libraries to the Feather RP2040
After downloading the Project Bundle, plug your Feather RP2040 into the computer's USB port with a known good USB data+power cable. You should see a new flash drive appear in the computer's File Explorer or Finder (depending on your operating system) called **CIRCUITPY**. Unzip the folder and copy the following items to the Feather RP2040's **CIRCUITPY** drive.
- **lib** folder
- **code.py**
- **Enceladus\_Hiss\_NASA.mp3**
Your Feather RP2040 **CIRCUITPY ** drive should look like this after copying the **lib** folder, **Enceladus\_Hiss\_NASA.mp3** file and the **code.py ** file.
## About the Enceladus Hiss mp3 File
The .mp3 file used for the white noise is a recording from NASA of Saturn's radio emissions:
> Saturn is a source of intense radio emissions, which were monitored by the Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth's northern and southern lights.
This recording is available from [NASA's Soundcloud site](https://soundcloud.com/nasa/cassini-enceladus-sound) and was featured in their [Spooky Space Sounds collection](https://www.nasa.gov/vision/universe/features/halloween_sounds.html). It is distributed with a [CC BY-NC 3.0 license](https://creativecommons.org/licenses/by-nc/3.0/).
## How the CircuitPython Code Works
Pins `D10` and `D11` and set to `True` to enable hardware on the PropMaker FeatherWing to work properly. `D10` enables the speaker pin and `D11` turns on the R pin for the RGB LED, which is used by the fan since it has a 5V output.
```python
# enable propmaker speaker output
enable = digitalio.DigitalInOut(board.D10)
enable.direction = digitalio.Direction.OUTPUT
enable.value = True
# enable fan pin
fan_pin = digitalio.DigitalInOut(board.D11)
fan_pin.direction = digitalio.Direction.OUTPUT
fan_pin.value = True
```
## The Mixer
An `audiomixer.Mixer()` object is instantiated to allow for volume control of the audio file in software. The value of `mixer.voice[0].level` can be a float from 0.0 to 1.0 and later in the code will be set by the rotary encoder.
```python
# speaker pin on the propmaker
audio = AudioOut(board.A0)
# create mixer instance
mixer = audiomixer.Mixer(voice_count=1, sample_rate=22050, channel_count=1,
bits_per_sample=16, samples_signed=True)
# attach mixer to audio playback
audio.play(mixer)
# open mp3 audio file
audio_file = audiomp3.MP3Decoder(open("Enceladus_Hiss_NASA.mp3","rb"))
# play audio file in first channel of mixer
mixer.voice[0].play(audio_file, loop=True)
# set mixer channel level
mixer.voice[0].level = 0
```
## NeoPixels
The NeoPixel pin on the PropMaker FeatherWing (`D5`) is instantiated as a `NeoPixel()` object. The `Pulse()` animation is used from the LED Animations library.
```auto
# propmaker neopixel pin
pixel_pin = board.D5
num_pixels = 35
pixels = neopixel.NeoPixel(pixel_pin, num_pixels, brightness=0.3, auto_write=False)
# define neopixel colors
RED = (255, 0, 0)
BLUE = (0, 0, 255)
# pulse animation
pulse = Pulse(pixels, speed=0.1, color=RED, period=3)
```
## Rotary Encoder
The rotary encoder and its NeoPixel are setup over I2C. Since `digitalio` and the standard NeoPixel library are being used alongside the `adafruit_seesaw` library, the `adafruit_seesaw` `digitalio` and `neopixel` portions of the library are imported as `seesaw_io` and `seesaw_neopixel` to avoid conflicts.
```python
# i2c setup for rp2040 feather stemma port
i2c = board.STEMMA_I2C()
# rotary encoder
enc0 = seesaw.Seesaw(i2c, addr=0x36)
encoder0 = rotaryio.IncrementalEncoder(enc0)
last_position0 = None
# encoder button
enc0.pin_mode(24, enc0.INPUT_PULLUP)
enc_button = seesaw_io.DigitalIO(enc0, 24)
enc_button_state = False
# encoder neopixel
pixel0 = seesaw_neopixel.NeoPixel(enc0, 6, 1)
pixel0.brightness = 0.2
pixel0.fill(BLUE)
```
## The Loop
In the loop, the Pulse animation is shown on the NeoPixels and the encoder button switches between `ctrl_mode` `0` and `1`.
```python
# run neopixel animation
pulse.animate()
# get encoder position
pos0 = -encoder0.position
# if the encoder button is pressed..
if not enc_button.value and not enc_button_state:
enc_button_state = True
# switch between control modes
if ctrl_mode == 0:
ctrl_mode = 1
else:
ctrl_mode = 0
```
## Turn Up the Volume
If `ctrl_mode` is `0`, then the volume of the audio file is affected by twisting the rotary encoder knob. Each position move either increases or decreases the audio level by `0.1`.
```python
# if control mode is 0..
# control the volume of the white noise
if ctrl_mode == 0:
# encoder neopixel is blue
pixel0.fill(BLUE)
# if the encoder moves..
if pos0 != last_pos0:
# if you increase the encoder
# increase value by 0.1
# maxed out at 1
if pos0 > last_pos0:
volume = volume + 0.1
if volume > 1:
volume = 1
# if you decrease
# decrease value by 0.1
# minimum value of 0
if pos0 < last_pos0:
volume = volume - 0.1
if volume < 0:
volume = 0
print(volume)
# reset the position
last_pos0 = pos0
```
## Turn Up the Brightness
If `ctrl_mode` is `1`, then the "brightness" of the NeoPixels are affected. The value affected by the rotary encoder is actually the red value of the RGB color value. Each position change by the rotary encoder increases or decreases the red value by `25`.
```python
# if control mode is 1..
# control the brightness of the neopixel rings
# actually controlling the % of red, not brightness directly
if ctrl_mode == 1:
# set the encoder neopixel to red
pixel0.fill(RED)
# if you increase the encoder
# increase value by 10
# max out at 255
if pos0 != last_pos0:
if pos0 > last_pos0:
pixel_level = pixel_level + 10
if pixel_level > 255:
pixel_level = 255
# if you decrease the encoder
# decrease value by 10
# minimum level of 25
if pos0 < last_pos0:
pixel_level = pixel_level - 10
if pixel_level < 25:
pixel_level = 25
print(pixel_level)
# reset the position
last_pos0 = pos0
```
At the bottom of the loop, the NeoPixel color value is set, followed by the audio mixer level value.
```python
# set the neopixel ring color
pulse.color = (pixel_level, 0, 0)
# set the audio volume
mixer.voice[0].level = volume
```
