Wire, Thread, Foil, Fabric, Paint

If it will conduct electricity, it will work as a touch sensor!

Connections:

The Toggle and Momentary boards have a solder hole located just below the sensor pad for attaching a wire to an external sensor.

The 5-pad breakout has pins numbered 0-4 on the left side of the board.

Sensor Pads

Attach the connecting wire to any conductive object or surface. That surface will become touch sensitive. Larger surfaces tend to be more sensitive. You will be able to sense through fabric, plastic glass and many other non-conductive materials.

Note that the wire will be touch sensitive too! Be sure to route any connecting wires away from areas where they might create an accidental touch input.
