A small script that allows Arduino to separately set the speed of two standard CPU fans. In order to control those fans the Arduino needs to generate a PWM signal at 25 kHz frequency. This is ...

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 ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

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 TC648B is a PWM fan speed controller with auto-shutdown, fan restart, and FanSense™ technology for fault detection. The device features over-temperature indication, efficient PWM drive, and it ...

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 ...

If you are interested in building robots, then it is certain that you need to learn how to control the speed and direction of a DC motor, and in one of our previous tutorials, we did just that using ...
