    I want to design a speed control for DC motor using uC..
    Problem Statement:
    There has to be two switch '+' and '-' to increase and decrease the speed of the motor.
    any uC will do.

    I need a program or atleast an algo to do this.
    Thank You..!!

    What you need is PWM (pulse width modulation).

    Do a Google search for PWM motor control, you should get 3 odd million hits. To narrow it down a bit add your favourite uC to the search string.

    Yes, as Alexr has indicated you need to look into PWM. You can search around this forum and find dozens of threads on the topic. Also there is much information on the Internet concerning the PWM.

    Thank You Fellas.
    I have already did the search but its nowhere given to using the speed control using two switches.
    Can anyone just simply provide me with the C program to speed control of DC motor with two switches to increase or decrease speed
    Thank You..!!

    Although I have not been on the site very long, I think you are kind of missing the point on this site.

    There are a large number of people here that are more than willing to help you out on your project. Even spend a great deal of time doing it. I think one of the main points is that they help you complete the work.
