This project demonstrates how to control the brightness of an LED using Pulse Width Modulation (PWM) on an Arduino Uno. The LED smoothly fades in and out by changing the PWM duty cycle on digital pin ...

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

In a previous article, I discussed LEDs in general and their properties. In this write-up, I want to give some examples of driving LEDs and comparing a few of the most commonly used methods. There is ...

Pulse Width Modulation is definitely the preferred method of dimming an LED with a microcontroller, but we were interested in hearing about a different method called Binary Code Modulation. BCM does ...
