Control of a DC motor using BS2 on a Professional Development Board supplied by Parallax Inc.is attempted. All the control modes like P, PD and PID are carried. The Pulse Width Modulated signal is used to drive the motor at desired speeds. This is a part of the Mechatronics course offered by Mechanical and Aerospace Engg. Dept. in Spring 2010.
