Hello Guys, My name is Mia. I'm designing a sound reactive light system.
Ideally, it looks like something similar to this,
For every heartbeat, the light will be turned on, and the light will be off when there isn't any heartbeat.
So I want to use a microphone to record my heartbeat and then plug it into the Shifty VU shield, then to the Arduino, I don't want to play from a mp3 player(only the mic).
The thing is, I can't find any shifty VU shield online, and just wondering if I could use any other things to replace the VU shield?
Thank you,
