Fortunately the Arduino UNO R4 provides some easy to use PwmOut class which provides more flexibility: The period needs to be defined in microseconds, so if you want to request a defined frequency in ...

To create extra channels of 16-bit PWM using the available 4 channels of 8-bit PWM on ATmega328P, this project requires the use of Timer0 and Timer2 in the microcontroller. However, since Arduino uses ...

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.

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.

This project uses the Arduino Uno PWM output to realize a fully isolated analog output with a range of 0..5 V or more. The use of an averaged PWM signal is not comparable with a real DAC, but it has ...

The purpose of this project is to provide a 4-20 mA output from a PWM signal generated by a microcontroller. One of the more interesting applications of this circuit would be to replace or to realize ...

There has been tremendous growth in digital control of power converters, and yet many power electronics students have limited experience with embedded systems. The Arduino Uno is an excellent learning ...

A new fully featured Arduino development board has been created called the Prestissimo Uno+ which is now available to back via Kickstarter with earlybird pledges available from just $20, AUS$28 or ...
