Still a work in progress…. Using anor an ATtiny microcontroller to translate sound (from a microphone or an audio jack) into light patterns.

– ATtiny microcontroller >> http://de.rs-online.com/web/p/mikrocontroller/6962614/
– 10uF capacitor
– power supply
Embarrassingly simple code:
Arduino listening to Mp3 player over audio jack
ATtiny listening to Mp3 player over audio jack
ATtiny listening to Mp3 player over microphone
Not very good sensitivity and translation yet.
