AT42QT101X Capacitive Touch Breakout Hookup Guide
Connecting the AT42QT101X Breakout Board
For an Arduino, make the following connections with jumper wires:
Mounting the AT42QT101X Breakout Board
One advantage of capacitive touch boards is their ability to be mounted to panels and detect touch through thin plastic, cardboard, etc. Using a drill or laser cutter, cut four 0.125 inch holes in the same pattern as the mounting holes on the breakout board.
You can create your own electrode by using foil, copper tape, or any other conductive material. Cut or shape the electrode and attach a wire between the electrode and the PAD pin on the AT42QT101X breakout board. For a secure connection, make sure to solder the external electrode together. The electrode can be almost any shape and size.
