The versatile DC motor speed controller project is based on PIC16F1825 microcontroller, its generate PWM pulse and also display the value on 2 digit 7 segment display, duty cycle adjustable 0 to 99 %, Frequency 1Khz, the speed of motor possible with help of two tactile switches. The board only generate and display the PWM, project required Mosfet on output to drive the motor. Check the circuit diagram for the Mosfet circuit.
Do u provide finished piece also ? 20 piece ready to use how much cost ?
