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 ...

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 ...

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 ...

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 very ...

Must admit I'm not up to speed with Matter, a way to standardise IoT elements. So it's welcome to see a basic introductory tutorial on using the wireless protocol on the Arduino website. With ...

The project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...
