Sensor tutorial 6: Capacitive touch (6 of 7)

FULL INSTRUCTABLE: www.instructab...
In this tutorial, I will go over the basics of capacitive touch sensing and how to use more than one capacitive touch sensor with an Arduino.
Pros for capacitive touch: Great signal, with or without an object between the plates. Customizable. Analog-type reading with digital pin. Minimal crosstalk (can probably be improved with better shielding too).
Cons for capacitive touch: Read time can slow down depending on capacitance. Contact with sensor is essentially required.
