Secrets of Arduino PWM
May 27, 2024 · The Arduino supports PWM on a subset of its output pins. It may not be immediately obvious which timer controls which output, but the following table will clarify the situation.
Basics of PWM (Pulse Width Modulation) | Arduino Documentation
Dec 15, 2022 · It is available in the File->Sketchbook->Examples->Analog menu of the Arduino software. Pulse Width Modulation, or PWM, is a technique for getting analog results with digital means.
Fading a LED | Arduino Documentation
Oct 2, 2024 · This example demonstrates the use of the analogWrite () function in fading an LED off and on. AnalogWrite uses pulse width modulation (PWM), turning a digital pin on and off very quickly with …
Use PWM output with Arduino – Arduino Help Center
Oct 31, 2024 · By default, the resolution is 8 bits, meaning that values passed to the analogWrite() function range between 0 and 255, which ensures backward compatibility with AVR-based boards.

Analog In, Out Serial | Arduino Documentation
Oct 2, 2024 · This example shows you how to read an analog input pin, map the result to a range from 0 to 255, use that result to set the pulse width modulation (PWM) of an output pin to dim or brighten an …
Analog Write with 12 LEDs on an Arduino Mega
Oct 3, 2024 · This example fades 12 LEDs up and the down, one by one, on an Arduino Mega board, taking advantage of the increased number of PWM enabled digital pins of this board.
Changing analogWrite () function frequency - Arduino Forum
Jun 30, 2025 · The source code for the analogWrite function is on your computer. You are free to modify the timer settings as you wish. Or, implement your custom timer code and do not use analogWrite.
PWM : digitalWrite() vs. analogWrite() - Arduino Forum
Sep 17, 2012 · digitalWrite () turns a pin on or off. analogWrite () turns the pin on and off very fast, so that the duty cycle is what you specify (as a percentage of 255). They are not interchangeable.
