“I saw a Youtube video along time(can’t find the video anymore) with someone using capacitive buttons. I found the github for the project but I didn’t just want to copy it. https://github.com/fb39ca4/kappa-pad
I wanted to use the Atmega32u4 for this project and the Arduino Pro Micro is perfect for this project. I bought the Pro Micro on Aliexpress for $2.98”
