Hi guys
am using atmega 328 chip adruino that has 7 pwm output ports
but what I exactly want to know is that these outputs would generate pwm signals automatically no matter what the inputs are?
or I have to do some sort of things to obtain pwm output signals am really confused about this
WHAT EXACTLY PWM i have read alot about it online but the idea is not really clear to me

thanks guys

 

atmega 328 has 6 PWM channels.

You can adjust the PWM using timer,please check page 40.
You can check the article you want used 'pwm' to search the pdf file.
