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 problems with the PWM part mainly because the ...

Whether you’re using a soldering iron or a table saw, ventilation in the shop is important. Which is why [Atomic Dairy] built a monster air cleaner called the Fanboy that looks like it should be ...

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 ...

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 ...

If you solder (and we know you do), you absolutely need ventilation, even for that lead-free stuff. Fortunately, [tinyboatproductions] has gotten into air quality lately and is here to help you with ...

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?

We've shown you a few automated irrigation systems, both large and small, but if you're an Arduino fan, you'll love DIYer Jouni's set-up, made out of a bucket, a submersible pump, and plastic hose. It ...
