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 ...

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 ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. With summer in full swing in North America, finding a way to keep ...

Most newer computer motherboards are equipped with pulse-width modulation controllers that can be used to control the revolutions per minute of the internal cooling fans. Whether one of your business ...

We love Arduino here at Hackaday; they’ve probably done more to make embedded programming accessible to more people than anything else in the history of the field. One thing the Arduino ecosystem is ...

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 ...

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 ...
