Arduino examples for avr-gcc with added Flake

This project is a very basic demonstration of how to compile and flash an Arduino Uno program utilising the avr-* tooling in the context of a Nix flake.

tl;dr

0. Configure nix (this is an exercise left to the reader)
   1. Install with the nix-installer
   2. Configure nix-direnv
1. direnv allow in project repository
2. Plug in an Arduino & find its port
3. Change ARDUINO_PORT in .env file (e.g. ARDUINO_PORT=/dev/ttyACM0)
4. make program
