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 ...

Based on esp8266-fan-control. Connect a esp8266 based board by USB to a linux based computer and control the fan via serial port (ttyUSB). The firmware is simple and intended to give control to the ...

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 ...
