[Runtimemicro] has the answer, at least if you are writing PWM code for the Arduino. Their free application lets you set a few parameters, visually see the results, and then generates code for you.

A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM. Recently, he revisited the issue and used his own PWM code to fix the problem. You can watch the video below.

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.

Universal (ish) Arduino grbl opto-coupler interface also works with logic-level pwm In adding an alternative cutter drive motor (‘spindle’) to an existing cnc machine, an electrically isolated pwm to ...

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 ...

After construction and testing, you can re-build the whole circuit in a small veroboard, with the help of one pre-programmed Arduino chip (Atmega328P-PU)! For more details about this, go to Arduino ...
