+CircuitPython Touch Input Example - Blinking an LED using a capacitive touch pad.

+This example is meant for boards that have capacitive touch pads, and no simple way to wire up
+a button. If there is a simple way to wire up a button, or a button built into the board, use
+the standard Digital Input template and example.
+
+Update TOUCH_PAD_PIN to the pin for the capacitive touch pad you wish you use.

+For example:
+If are using a BLM Badge and plan to use the first pad, change TOUCH_PAD_PIN to CAP1.
