Nanofan Arduino Fan Controller V1
thingiverse
Yet another PWM-based fan controller using an Arduino Nano, arcade button, N-channel MOSFET, and 7805 voltage regulator. I designed a case for an upcycled 120mm PC fan that uses three speeds: ON, ON MORE, and ON MOSTEST. Three different color LEDs on the faceplate indicate the current speed. All case parts are snap fit, requiring no screws or glue. The source code and Bill of Materials can be found at the project's GitHub page [here](https://github.com/dmwatson/nanofan_controller). The fan grilles I used were from [this thing](https://www.thingiverse.com/thing:263573), but they are not necessary - they do work quite well. I've also included the OpenSCAD source file.
