PWM Control: The prevalent method currently used for controlling fan speed in PCs is low-frequency PWM control. In this approach, the voltage applied to the fan is always either zero or ...

Arduino Fan Speed Control using Temperature Sesnor . This project consists of three sections. One senses the temperature by using humidity and temperature sensor namely DHT11.The second section reads ...

The wire is normally pulled up to 5-12 V, and to reduce the fan speed, we should pull it down. Pulling it down all the time would tell the fan to turn at its lowest speed. Leaving it high lets the fan ...

We set the potentiometer pin as 0 (A0 on the Arduino Uno board), the CONTROL variable is the voltage that is used to cotrol the led brightness of the speed of the fan. In the setup() function 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 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… ...
