Connect4

Inspired by and based on the code of https://www.thingiverse.com/thing:3785812 a handheld connect4 game with computer opponent. I added a scoring system using the far right column that is officially unused in a 7 x 6 connect4 setup.

I used an [Adafruit Trinket M0](https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino) and a flat Li-on battery I rescued from a broken e-reader. I used the [Trinket Pro backpack](https://learn.adafruit.com/adafruit-pro-trinket-lipoly-slash-liion-backpack) to charge the battery. To control the game I implemented a [rotary encoder](https://learn.adafruit.com/rotary-encoder) + pushbotton.
