I wrote this when I could not find Arduino code online that could accurately and reliably read 25kHz pwm signals. For reliable PWM you must handle the following edge cases: 100% or 0% PWM signal with ...

Tiny basic PWM The ATtiny85 microcontroller allows us to generate an analog output using PWM. The ATtiny85 microcontroller has two timers that can be used to generate PWM signals. The first is Timer 0 ...

The Atmega 328P chip in the Arduino Uno has three PWM timers (known as Timer 0, Timer 1, and Timer 2) controlling six PWM outputs. Each of the timers has a prescaler that generates the timer clock by ...

This study presents the development of a LASER power controller using pulse-width modulation (PWM) technique for the 3-axis computer numerically-controlled (CNC) LASER Machine. This includes the use ...

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.

Here’s an Arduino library that will let you drive a very large number of LEDs. [Elco Jacobs], an electrical engineering student, is the author of the library. He has a work-study job that has… ...
