My final year project is to design a microcontroller based digital DC motor speed controller where I am assigned the software part...
I plan to use the 16F877 microcontroller from microchip. My problem is I'm new to it and I don't understand how I can control the voltage and get my desired speed of motor. How how does the feedback circuit from motor interact with the microcontroller as a closed loop system?
