The NeoPixel strip is attached as follows:

NeoPixel DI to Feather pin 13
+5v to red wire spliced to on/off switch
G to black wire spliced to on/off switch

Remember, NeoPixel strips are directional. Be sure you're soldering to the "in" end of the strip (DI) and not the "out" end (DO).

The IR Sensor is attached as follows. With the sensor facing up and the legs down, and the bump facing you:

Out (leftmost pin) to Feather pin A0
G (middle pin) to G
Power (rightmost pin) to 3V

Plug the battery into the on/off switch and the switch into the board.

Battery Charging

This project is designed to run from an onboard battery. The Feather microcontroller has onboard battery charging, so you can permanently install your battery and recharge it by plugging in a USB cable to the Feather.

However, with this wiring setup, the battery will not charge with the on/off switch turned off, since the switch is between the battery and the controller. So when you plug in your table to charge, be sure the switch is clicked to "on".

CircuitPython is a derivative of MicroPython 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.

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 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.

Copy Text

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.

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 doesn't even show up as a disk drive when installing CircuitPython, try loading this 'nuke' UF2 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.

Download flash erasing "nuke" UF2

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.

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

Your Feather RP2040 CIRCUITPY drive should look like this after copying the lib folder and the code.py file.

How the CircuitPython Code Works

First, we import all the necessary libraries and animations we'll be using.

Check out the CircuitPython LED Animations Library guide for more info on adding your own animations.

NeoPixel Setup

Set your total number of pixels here. If you soldered to a different pin than 13, you can change the pin number here as well.

NUMBER_OF_PIXELS = 85 
pixels = neopixel.NeoPixel(board.D13, NUMBER_OF_PIXELS)

NUMBER_OF_PIXELS = 85 
pixels = neopixel.NeoPixel(board.D13, NUMBER_OF_PIXELS)

Speed & Brightness Control

This code includes 8 brightness levels and 7 speed levels, which can be selected with buttons on the IR remote. You can edit them, add or subtract here.

# Define the brightness levels and their corresponding values
# Start at a non-blinding brightness.
BRIGHTNESS_LEVELS = (0.025, 0.05, 0.1, 0.2, 0.4, 0.6, 0.7, 0.8, 1.0)
brightness_index = 2
pixels.brightness = BRIGHTNESS_LEVELS[brightness_index]

pulsein = pulseio.PulseIn(board.A0, maxlen=120, idle_state=True)
decoder = adafruit_irremote.GenericDecode()

SPEEDS = (0.25, 0.125, 0.1, 0.08, 0.05, 0.02, 0.01)  # Customize speed levels here
speed_index = 4

# Define the brightness levels and their corresponding values
# Start at a non-blinding brightness.
BRIGHTNESS_LEVELS = (0.025, 0.05, 0.1, 0.2, 0.4, 0.6, 0.7, 0.8, 1.0)

speed_index = 4

Animations

Here is where you set up and define your animations. You can edit colors, spacing, and lots of other variables until the animations do exactly what you want.

Pressing the left and right arrow keys will cycle through the animations in this list. You can add, subtract, or reorder them so the animations appear in the order you want.

Solid Color Keys

The 0-9 buttons will select solid colors from the rainbow, with 0 as "black", which will turn the LEDs off. You can edit the colors, or assign different animations to the buttons by editing this code.

SOLID_COLORS = {
    CMD_0 : color.BLACK,
    CMD_1 : color.RED,
    CMD_2 : color.GREEN,
    CMD_3 : color.WHITE,
    CMD_4 : color.BLUE,
    CMD_5 : color.PINK,
    CMD_6 : color.YELLOW,
    CMD_7 : color.PURPLE,
    CMD_8 : color.TEAL,
    CMD_9 : color.ORANGE,
    }

SOLID_COLORS = {

    CMD_8 : color.TEAL,
    CMD_9 : color.ORANGE,
    }

Main Loop

The main loop starts with the while True: line. First, the code checks to see if a button has been pressed. If you open the serial monitor and press some buttons on the remote, you'll see a readout of which code is being transmitted.

Finally, the code tells the NeoPixels how to behave when a button is pressed. This is the part you'll edit if you want to customize your button layout.
