For this project I built an addressable LED grid out of 1000 ws2813 LEDs. I painstakingly attached the LEDs to a fishing net using individual zip-ties and a grid of holes I fashioned out of poster board. I’m using the FastLED library to control the individual LEDs. So far I’ve set up a few different light show configurations.
My favorite has got to be using a sound sensor to read the amplitude of a near by speaker and output the lights proportionally to the sensor reading.
I’m going to sync these up to some various inputs like the Myo armband and/or the Leap motion and try and see if a couple people wearing the device can have an interactive dance party!
