This project uses the Arduino Nano 33 IoT, the Arduino IoT Cloud, E1.31 (streaming DMX) and Alexa to control 12 volt WS2811 LEDs.

Ten-year old nephews are particularly impressed when they can change the colour of the outdoor Christmas lights from a tablet.

Do you know of the famous WS1012 LEDs? The PL9823 is the cheapest LED that uses the same protocol of the WS1012. Let's blink LEDs!
