After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

The sensor shown here is essentially two plates mounted side-by-side, attached to an Arduino Nano using the Capacitor library which uses just two pins, one digital and one analog.

The design was prototyped using an Arduino, which controlled an LED through feedback from an ultrasonic proximity sensor. The LED would flash into the user’s peripheral vision, glowing when the sensor ...
