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 ...

Fan Control is a great tool for doing exactly what its name suggests, giving you complete control over your system's fans, including your CPU and GPU fans, plus any water cooling pumps that you may ...

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 ...
