Hi guysam using atmega 328 chip adruino that has 7 pwm output portsbut what I exactly want to know is that these outputs would generate pwm signals automatically no matter what the inputs are?No there is no automatic pwm output. you use the arduino analogWrite command to generate a PWM signal on an arduino output pin.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 meHere is the Arduino reference info on the analogWrite statement and it includes some simple examples: http://arduino.cc/en/Reference/AnalogWriteLeftythanks guys
