Hey

i am searching For control motor by using PWM With AVR

so can i generate Voltage by using PWM ????

i had work alot but i failed

Firstly, You dont generate voltage using PWM.
You merely control how much of the time the motor is connected to your supply voltage, i.e the duty cycle.

the first two entries found by searching google:

You should allways check google, and search the forums before posting.

I asked About AVR coz i think it can generate voltage Because it has PWM Hardware

It is my first time To use AVR i used PWM by software only

generally i have understand All about PWM Now

Thanks For all

Its exactly the same principle whether done by hardware, or by using software delays.

Plenty of PICs have PWM hardware too

And some PICs have more than one hardware PWM output too
