Nanofan Arduino Fan Controller V1

Yet another PWM-based fan controller using an Arduino Nano, arcade button, an N-channel MOSFET, and a 7805 voltage regulator.

I designed a case for an upcycled 120mm PC fan. It uses 3 speeds: ON, ON MORE, and ON MOSTEST. Three different color LEDs on the faceplate indicate current speed.

All case parts are snap fit. No screws or glue required.

The source code and Bill of Materials are located at the project's GitHub page [here](https://github.com/dmwatson/nanofan_controller).
