Code for pulling text from an API endpoint and scrolling it across a matrix
- Configure the defines for your chosen LED pin, Matrix dimensions colour mode, an optional status LED pin
- Configure a variable for the HTTP API URL you want to call
- Tweak the code if you want to display a different key than "message"
This works on an ESP32 with Wifi running Arduino. Works (barely) on a 32x8 matrix (may have to shave a bit and go for 30x7) on an Arduino Nano or similar
If compiling using the Arudino IDE, make sure you have LEDText, LEDMatrix, ArduinoJSON, FastLED
