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 ...

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 ...

Arduino fans, this project turns TVs on when you want them off. It makes a perfect April Fools' Day joke or gag gift—or, in the spirit of Evil Week, use it anytime of year to drive people crazy. You ...

I loves me some Arduino. The only thing I don’t love — and I’m sure many of my fellow Arduino tinkerers would agree with me here — is buying or building a new shield (read: add-on board) every time I ...
