Fortunately, with a bit of electronics hacking, you can get those fan blades whirring without having to flip a switch. It’s a fairly simple project, too: just hook an Arduino Uno up to a motion ...

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 ...

Whether you’re using a soldering ... the sound doesn’t directly control the solid state relay used in the fan controller. When the microphone equipped Arduino detects enough noise, it will ...

In this quick Arduino tutorial I will explain how you can control a relay using the Arduino Board, one 1K and one 10K resistors, 1 BC547 transistor, one 6V or 12V relay, one 1N4007 diode and a 12V fan ...

Arduino enthusiasts looking for a little inspiration for their next Arduino project may be interested in this Arduino music machine which is being created and uses 7 lasers and 42 fans to create ...
