Precise illumination control of matrix light-emitting diode (LED) headlamps is crucial for both energy efficiency in electric vehicles and driver safety. Enhancing energy efficiency extends the range ...

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 ...

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 ...

This library is to control the I2C PCA9634 PWM extender. The 8 channels are independently configurable in steps of 1/256. This allows for better than 1% fine tuning of the duty-cycle of the PWM signal ...

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 ...

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 ...

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… ...
