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 ...

For one, 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 start a timer that keeps the fan ...

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 ...

Once control of the fan was sorted, [tinyboatproductions] decide to add an OLED display to show the fan speed and power condition, which is a nice touch. Be sure to check out the build video after ...

An Arduino controller app (Here’s one for the iPhone and one for Android devices) An idea of what you’re trying to achieve A little technical know-how! One of the great things about the ...

Here's a project for Arduino fans with an old iPhone sitting in their junk drawer. Following these instructions from Will O'Brien, you can craft a remote start system that's triggered by SMS. The ...

The Arduino hardware autonomously controls the rocket stabilisation but rather than have a rocket drone, there’s also manual control and override built-in as well.

And if you love Arduino and their host of multi-skill level electronics projects, then you’re probably also a big fan of Codebender, the web’s one-stop-shopping for all the coolest Arduino ...
