Detecting touch on a touchpad

In this recipe, we will learn how to detect when a touchpad is touched and to print a message each time this event occurs. The Circuit Playground Express comes with a number of touchpad connectors that can be attached to all sorts of objects.

Essentially, anything that can conduct electricity can be used as a way to interact with your device. You can use wires, conductive thread, fruit, water, or copper tape to interact with your device.
