How to use a stepper-motor from old disk drives
21. February 2009 - 13:51 — adminWhy and how to use components from old disk drives?
DC motor speed control using PWM
25. June 2008 - 20:20 — adminDC motor speed control based on PIC16F867.
The circuit is using PWM with frequency about 10kHz, which does not make a noise in the motor. This project can drive motor with 1A current without heat. The motor speed is controlled by potentiometer which is connected to ADC input of PIC16F867.
BitESC - motor controller
21. April 2008 - 18:41 — adminThe BitESC is a small electronic speed controller for those little RC cars like the MicroSizer / BitChar-G. It can be used in a small RC plane to have some control over the speed of the motor.
