This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

WARNING!! The circuit diagram discussed in this project is only for educational purposes. Be advised that working with 220V AC mains voltage requires extreme precaution and safety procedures should be ...

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 ...

Re-Engineering a YLFC700 Fan Speed Controller (TRIAC based). This controller was originally sourced from an Xtrodinair Apex 42 Fireplace. The problem with the controller is that the slide ...

This repository contains a reversed engineered based source code of the /usr/sbin/ubnt-fan-speed executable found running as a service on some ubiquiti applicance (i.e: UDM Pro). This work is based on ...

Typically, CPU fan noises are heard when you reboot your PC (the whirring sound you may have heard upon startup) and it goes on to decline as the startup process completes. The purpose of fans on your ...
