Project Audio

For this short project, I made a little audio thing that responds to both capacitive touch and nearby electric fields to shift the pitch output of a speaker.

To be made

How to Play

• There is a potentiometer next to the speaker to control its volume
• There is a switch to toggle between the capacitive touch and nearby sensing.
• The curled up wire is the capacitive touch sensor
• The straight wire is the nearby sensor.
