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 ...

Arduino is a do-it-yourselfers dream that allows you to create a true smart home experience tailored to your needs. Check out how to use Arduino to build the smart home you want.

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 ...
