Controlling an LED matrix from a website hosted on a raspberry pi

Prerequisites:

• 2 64x32 RGB LED Matrix
• Adafruit RGB Matrix Bonnet for Raspberry Pi
• Any normal size raspberry pi (so that the bonnet can fit on top of it)

Running the website

1. Boot your Pi with raspbian and with a network connection
2. Follow the wiring guide from @hzeller (link)
3. Install docker and docker-compose
4. create a .env file in the same directory as rpi-led-controller to match your led sign settings. For example, a single 32x64 matrix would have the below values:

LED_MATRIX_ROWS=32
LED_MATRIX_COLUMNS=64
LED_MATRIX_COUNT=1

If you have a single matrix, set LED_MATRIX_COUNT to 1, for a chain of 2, set it to 2 and so on.

5. Run the website with:

docker-compose up

6. After some time, the website should appear, accessible from port 80 on the pi:
