“This is a simple to build motor controller. It is handy for many projects using a motor controlled by a micro-controller. It can be used as an Electronic Speed Controller (ESC) and has forward and reverse control. It can be used in robotics, remote control projects, portable vehicles and most things motorized. It also uses very little parts. All of this is made into a tiny package to fit in your DIY projects. This circuit is based off of a Driving Bigger Loads circuit in one of my books. That circuit only used one MOSFET and a diode. It is meant for a micro-controller to control a motors speed. To be able to go in reverse I just added a DPDT relay and another MOSFET, diode pair to control the polarity switch. I hope you enjoy this instructable.”
