"Controlling the Brightness of an LED" ..
This example should give you basic idea on P(ulse)W(idth)M(odulation) generated by a microcontroller ..

Re: PWM

which microcontroller u r using??in 8051 u can use any timer with auto reload mode and enable the interrupt for this timer.then simply write the interrupt routine as u want.

Re: PWM

if u are using PIC controller and PIC BASIC Compiler it is very easy to generate PWM on any pin using pulsout command

Re: PWM

which micro u are using? if u are using AVR it is very ieasy to make pwm u should study its timers.see it in its datasheet.

PWM

if i using PIC12c508 & 12f508a? is it very easy too?
but i can't understand ,how to adjust cycle.because,
it had one timer and no interrupt . is it right?

PWM

u have to set variable on time and off time. initially increase on time and decrese off time and vice versa. plz try.
