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 ...

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.

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 ...

Now the speed can be controlled with a pot. 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.

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 , ...

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 ...

Okay, all you Arduino fans, now that you've mastered the basics of blinking LEDs, driving motors, and monitoring environmental sensors, you're ready for something a little more interesting, right ...

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 ...
