sir, i want to interfaceto 89c52 and control the speed of the dc motor, i m not getting idea, how to control dc motor speed by using 89c52
You could try this: Press the 89c52 firmly against the motor spindle to slow the motor down, release to speed up. To stop the motor short the supply across a couple of the pins. Implementation time: 2 seconds. Cost: $4.95 Job done!
Hallo Stefan! Oh, I would be very happy if i could solve all my problems in that straight way. Ulf
OK, time for a fresh start... More details are required, let's start with: - Details of the DC motor. - How the motor is to be driven. - How the motor speed is monitored. There are endless variations in each case. If you have not made up your mind about these details, then tell us about the application.
