Hello Guys, My name is Mia. I'm designing a sound reactive light system. Ideally, it looks like something similar to this, https://www.youtube.com/watch?v=cRJcrWXp--w
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, :D :D :D
