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 ...

A temperature-controlled fan automatically adjusts its speed based on the surrounding temperature. This project uses an LM35 temperature sensor and PWM (Pulse Width Modulation) control to regulate the ...

This project demonstrates how to control a fan (simulated with an LED) using an Arduino Uno and a temperature sensor. Below 25°C → Fan OFF 25°C to 30°C → Fan runs at 50% speed (PWM) Above 30°C → Fan ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

This setup will let you monitor Play Station 3 temperatures and throttle the cooling fan accordingly. [Killerbug666] based the project around an Arduino board, and the majority of the details about ...
