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) ...

Arduino library to generate a fast PWM signal on an output pin at maximum frequency. Examples included. FastPwmPin provides a means to generate a high frequency PWM signal on one specific output pin.

This repo demonstrates how to work with an Arduino's PWM outputs in a clean programmer-friendly way. It packages all the low-level interaction with timer clocks that underly PWM functionality, ...
