This Arduino sketch will connect your device to the WiFi network, receive pixel data and output it onto your LED Matrix.
The LEDs are controlled using the library FastLED this library supports all major LED chipsets.

Troubleshooting

  • Missing library
    Ensure you have downloaded both required Arduino libraries:
    Arduino WebSockets: https://github.com/Links2004/arduinoWebSockets FastLED: https://github.com/FastLED/FastLED
  • No LEDs light up
    Double check wiring.
    Double check FastLED setting. read more Check status pixel, see below Confirm web interface is connected and sending data.
  • Can't find devices IP
    Open the console monitor in Arduino software and set baud rate to 115200. Restart/reupload the sketch and you should see the connected IP address.
  • Something else
    If you are having any problems please log an issue.

Status pixel

Pixel zero is used as the status pixel when no data is being cast.

  • Yellow: Arduino booting
  • Orange: WiFi attempting to connect
  • Green: Ready
  • Blue: Device connected, but no data yet received
  • Red: Received bad/unexpected data
