Built as a solution to provide analogue inputs to the Raspberry Pi without the hassle of setting up a breadboard each time. The proto HAT also breaks out the Pi's GPIO, so extra-long headers can be used to attach Pimoroni's Blinkt or Mini Black Hat Hacker.

With a few spare rows on the proto HAT, I added a trio of LEDs so that I could work with relatively simple scripts to get my Python up to speed. The pots and switch can be used to alter values of the outputs like the colour/brightness/blink speed of LEDs, or can just as easily connect with anything else attached to the available GPIO pins.
