Capacitive Touch Playground for CircuitPlayground

myminifactory

I wanted an input device to further play with the Capacitive Touch capabilities of AdaFruits CircuitPlayground.  This model is just the base and is designed to be used with Vladimir Mariano wonderful Circuit Playground Screw Terminal Mount.  This is a larger model and requires a print bead capable of printing 195mm X 150mm. The 7 pipe lengths used were 126.5mm, 112.6mm, 100.3mm, 95mm, 84.5mm, 75.2mm, and 67mm respectively.  While the idea was to create a capacitive touch interface for many experiments the first example mapped the inputs to the music scale from 262Hz to 494Hz so I set the pipe lengths to relate to the wavelengths of those frequencies
