Traditional fans run continuously or require manual control, often leading to energy waste. This project creates a smart solution: a temperature-sensing fan controller that turns ON/OFF or adjusts ...

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 ...

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 ...

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 ...

From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...

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 ...
