Wii Remote Digital Graffiti

Set up Python libraries for Wii remote communication.

1. Open Terminal on Raspberry Pi.
2. Update package lists: sudo apt-get update
3. Install cwiid library: sudo apt-get install python3-cwiid
4. Install pygame: sudo apt-get install python3-pygame
5. Verify Bluetooth is enabled on your Pi.

Pair the Wii remote via Bluetooth.

1. Create a Python script to pair the Wii remote.
2. Run the script and press buttons 1 and 2 on the Wii remote simultaneously.
3. Wait for the LEDs to stop flashing (indicates successful connection).
4. The Wii remote is now paired with your Raspberry Pi.

import cwiid

print("Press 1+2 on Wii Remote...")
wiimote = cwiid.Wiimote()
print("Connected!")

wiimote.led = 1
print("Ready to use Wii Remote.")

Create a Python app that tracks IR and draws.

1. Enable IR tracking on the Wii remote (it uses an IR camera).
2. Set up an IR source (infrared LED or lit candle) as a pointer.
3. Create a pygame window to display the drawing canvas.
4. Map Wii remote IR coordinates to screen positions.
5. Draw lines as the IR source moves.
6. Use Wii remote buttons to change colors or clear the canvas.
