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 ...

The wiper of the 10K potentiometer is wired to A0 of Arduino (5V-A0-GND), while anode (A) of the test LED is linked to D5 through a 220Ω-470Ω resistor and cathode (K) to GND. #include ...

I wanted to make an LED string lightsaber. The programming and prototyping was fun, but after seeing how much time, effort and money would be needed to scale the project into a 'blade', I decided NOT ...

Wire an Arduino to a couple of pots, as described in pwm_explorer.ino. Upload pwm_explorer.ino to the Arduino. One pot controls the frequency, and the other controls the duty cycle. They flash the ...

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 ...

While Arduino traditionally uses C++ like code, you can actually program and control Arduino boards using Python through a powerful protocol called Firmata. This comprehensive guide will show you ...

PWM pins work the same way across all Arduino boards, so you don't need to go out of your way to buy a Mega if you already have a board supporting PWM. On the Uno, Nano, and Mini, the PWM pins are ...

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 th… ...

Software The Arduino IDE or The PlatformIO extension for Visual Studio Code How to Use an RGB LED Module Using the Digital Method This method only works on Arduino boards with a GND pin next to pin 13 ...
