This project creates a system where three LEDs' brightness levels are controlled based on how quickly two pushbuttons are alternately pressed. The project consists of: 1-) A Linux kernel module • ...

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 ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...

This project implements an LED Intensity Controller using a microcontroller (PIC24F16KA101) and Python. The system allows users to: Control the brightness of LEDs using a potentiometer. Blink LEDs at ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...
