In this video I show off a 6-button capacitive sensing board which allows us to detect when any of the six buttons have a finger or similar neaby. The board is smart and adjusts itself to whatever metal you connect to the pads and it will also only allow one button to be triggered at a time so you can run your wires fairly close to each other and it will bias itself to the one you're most likely touching.
Very cool and flexible part for your engineering builds!
