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 ...

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 project simulates a temperature-controlled fan system using an Arduino Uno and a TMP36 temperature sensor. The fan (represented by an LED) turns on when the temperature exceeds 30.5°C. The TMP36 ...

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 ...

A fandriver is easy to do with an Arduino as an active ontroller. In this circuit, the Arduino Pro-Mini has been chosen, it is one of the smallest versions and for almost no money for sale. To measure ...

I was wondering about a temperature controlled case fan (80mm or 120mm) that has its own temperature sensor (not controlled by the motherboard) to control its RPM. Are all of them like this or are ...

As connected as we are, reliable and affordable internet is still a luxury in the far reaches. [kohleick’s] country home is not just remote; with temperatures dropping to -30C in the winter, it’s ...
