Working on motor control had always been my passion. For this project, I thought of working on something simpler in hardware. Hence it came out as a speed closed loop control of DC motor using back emf sensing.
The GOduino II is a self-contained programmable controller for wheel-based robots. It's an Arduino Uno clone plus an L293D motor driver for under $20.

PID controller using Back EMF as the Control Feedback
By software control, I mean replacing the Polulus with plain H-bridges (e.g.
As promised, here are some more details on how I implemented back-emf to control the wheel’s rotational speed.
