Hello there,
I just got my new Arduino Uno WiFi and this DMX interface: https://www.seeedstudio.com/grove-dmx512-p-1447.html
I connected everything and I am able to control the lights over the serial monitor using the DMXSimple library. My intention was to control them via a web interface from a mobile device for example, but I have absolutely no idea how and where to begin.
Maybe someone can give me a hint?
