Infrared Tracking Robot

hi everyone, iam bit very confused by the way i messed up with my project...i perfectly programmed my mirocontroller ,but i made tat for stepper motor ,which became flop. now iam trying to do it with a dc motor, but iam not sure of how a dc motor works and the compatability of the microcontroller and the dc motor.so, here is my question. can i use my same program which i used for stepper motor (sounds absurd!)or i have to modify my program... the also i need some info on driver circuit on dc motor control...here is my program....if some one can modify my program that will be gr8 help ....

Google "H-Bridge"

The most common and IMHO best way to control motors is with an h-bridge motor controller circuit. Google it to find tons of data.

No, you can't use your stepper motor code to run a DC motor. A stepper motor depends on a digital sequence like...

1010
1001
0101
0111

to energize the windings of the motor in the correct sequence to turn the motor by one increment. Totally different concept than DC motors.

oh... also Google PWM, Pulse Width Modulation to see how to get speed control of your DC motors.
