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 ...

This project implements a temperature-based fan speed controller using an Arduino Uno. The system adjusts the fan speed based on the ambient temperature, providing efficient cooling and energy ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

The 16-channel 12-bit PWM/Servo Driver, PCA9685, is an ideal module for precise control of multiple PWM outputs that are commonly used to control servos, LEDs, and other devices in applications such ...

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 ...
