DIY Arduino/Leonardo CNC Spindle Speed Control

This is the Arduino version of the Raspberry Pi video that I did earlier. IMO for most folks this is a more cost effective solution. All parts can be found on EBay, and depending on what you already have should be buildable for less than $45, and in a bare bones version can be up and running with just a couple of hours effort. Code for this Arduino project can be found at https://github.com/jmharvey1/Arduino-CNC-Speed-Control If you are building this project, you might also want watch https://youtu.be/PA9UYz__dcc It contains sensor setup tips not shown in this video
