Have neopixels light up with the rythm of music!
An app written in Processing will listen for audio. If the levels reach beyond a given threshold - an event is sent via Serial over to an Arduino.
The Arduino is listening for events sent by the Processing application and will light up a strip of NeoPixels.
- Follow Adafruits guide to power the NeoPixels
- Without starting the Processing application, upload the Arduino code on to an Arduino
- Start the Processing application, look at the output in the console to find which index your Arduino have in the list of Serial devices.
- Modify the Serial-constructor to use a suitable index
- Run the Processing application
