 4  CircuitPython Touch Input Example - Blinking an LED using a capacitive touch pad.
 5  
 6  This example is meant for boards that have capacitive touch pads, and no simple way to wire up
 7  a button. If there is a simple way to wire up a button, or a button built into the board, use
 8  the standard Digital Input template and example.
 9  
10  Update TOUCH_PAD_PIN to the pin for the capacitive touch pad you wish you use.
11  
12  For example:
13  If are using a BLM Badge and plan to use the first pad, change TOUCH_PAD_PIN to CAP1.
