Provide me logic/circuitry and code for controlling motor

motor control

hii
i am using a two wheel drive for my remote cntrolled car.for this i m using a PIC16F87X for controlling the motor.can anyone help me with the logic/circuitry and the code for controllling the motor.i am not using any type of sensors.

Re: motor control

hi,
which kind of motor are u using??

dc motor normally used) then u can connect a H bridge ic or construct one for simple forward and reverse control of the car
stepper motor: Here u need a driver circuit,which is a simple transistor drive for the coil excitation.

In the dc motor u'll be having less precise control, but in the stepper motor u'll be having precise control, and u can decide the step size also .

But with a stepper motor u'll be using 4 I/O lines and the only 2 in the dc motor( but i dont think this should be a problem with an 877)

Re: motor control

If you are using brushless DC motor. There is a circuit diagram and code for pic16f877 on microchips' site : www.microchip.com

look at that site !

hi sam
i am using the dc motor and will be doing with H-bridge circuit.can u give me the code for controlling the motor from PIC16F87X.i am also planning to make the car wirless .For that i am making an infra red transmitter receiver.but in this i hav to keep alinged transmitter and receiver in the same line which is a problem.can u suggest me something else.
