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 ...

We’ve covered plenty of persistence of vision (POV) displays before, but this one from [Vadim] is rather fun: it’s built on top of a PC fan. He’s participating in a robot building competition soon and ...

Hot hardware is unhappy hardware, and with temperatures soaring to new highs across the globe, where you place your PC’s fans plays a crucial part in how efficiently your precious components perform.

[royboy] from the Arduino forum has recently made a post showing off his Arduino / PC ambient light system. The system is simple to wire up and easy to use, as long as your video is being sent from a ...

Your PC will have default fan settings, telling them how fast they should spin at any given temperature value. These are known as fan curves as the higher the temperature of your PC or specific ...

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 ...
