In this tutorial, T.K. Hareendran shows us how to set up an interleaved PWM output on an Arduino Uno. He then uses different techniques to validate that the desired result is achieve.

The Arduino library gives you a wrapper called analogWrite — especially handy if you are not using an Atmel CPU where the same abstraction will do the same work.

Note that humans perceive the brightness change non-linearly. The human eye responds to light in a logarithmic fashion and has a better sensitivity at low luminance than high luminance. If you do not ...

AnalogWrite uses the various timers on an Arduino to put out a pwm waveform – with 1/256 (ish) resolution. And it offers 0% and 100%. This is naturally-available with the timers that the Arduino IDE ...

Community collaboration is a great thing. Take the Arduino PWM library for shift registers. Some folks at the Arduino forum pitched in and helped [Elco] trim off a bunch of clock cycles by using ...

Want a fast PWM quickly? – consider Arduino I have been discussing control algorithms for a power supply and idly looking for some easy hardware on which to try the technique – hardware small enough ...
