I designed and built a simple "StackLight" for Autodarts using WLED. Unlike most setups that use WiFi, this one uses a USB connection for both power and changing colors.
I call it "dumb" because it doesn’t track the actual game. It only shows the status of the board, so you know when it is safe to throw:
I made this for my darts club. Sometimes the board gets stuck in "takeout" mode, and this light helps players avoid throwing darts that won't count.
You do not need to perform any software setup; simply run the script, and it will work if your PC recognizes an ESP32 connection.
You will need the following parts for this build. Length of Strip and Diffuser is 19cm.
