    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.

    atmega 328 datasheet.
