A sophisticated fan control system built with Arduino that provides precise temperature control through either PID control or custom fan curves. This project is perfect for cooling applications where ...

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 ...

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 ...
