The Arduino Mega's PWM pins are digital output pins located on D2 to D13 and D44 to D46, coming to a total of 15. While they function as normal digital pins that can switch a component either ...

Here the “analogWrite” function can be used to set the PWM duty cycle. To regulate the brightness level of an LED with PWM, just connect it to one of the PWM channels (with a 1K resistor in series) ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...
