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 ...

This project demonstrates a contactless, gesture-based fan switch using an ultrasonic distance sensor, Arduino Uno, and a relay module. By simply waving a hand within a certain range (5–12 cm), the ...

This project uses two Arduino boards to control the speed of a DC fan using a potentiometer. Three LEDs indicate different speed ranges: red for slow, green for medium, and blue for fast. The serial ...

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 ...
