Capacitive Touchscreen / Arduino Interface

I figured out how to mimic the capacitive response of a human finger for use with capacitive touchscreens! This provides a hardware means to interface with touch-enabled devices. The mechanism is operated by an Arduino microcontroller.

In the end, we ended up using a software solution to emulate finger taps instead – though it’s still cool to know that this somewhat-inelegant hardware solution is always an option!
