Today I tested out my 3D capacitive sensor.
[image]I ran the sample code, and received x, y, and z coordinates!

Today I built even bigger capacitive switches by finding and taping together aluminum foil and cardboard. [20150223_111313.jpg]
Today I built my Arduino capacitive switch.
I started by downloading the library needed here:
