Closed loop speed control of DC motor using back emf sening

http://www.techelex.com/2011/05/closed-loop-speed-control-of-dc-motor.html 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.

As promised, here are some more details on how I implemented back-emf to control the wheel’s rotational speed. http://robidouille.wordpress.com/2009/09/20/back-emf/
