A PIC16F676 microcontroller based fan speed controller unit which is capable of controlling three groups of 12V DC fans with using temperature feedback. You can set the threshold temperature for each ...
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 ...
Deciding between PWM and DC case fans can be confusing, but it’s important for the optimal performance of your computer. In general, PWM fans are quieter, more controllable, and more durable than DC ...
