The objective of this experiment is to use a PIR motion sensor to control a fan as a on/off switch. The PIR sensor will be used to detect if there is someone in front of the fan where then the raw ...

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 ...

Here we are going to build a motion-controlled fan project using ATmega328 and RCWL-0516 Doppler RADAR Motion Sensor. This project will eliminate the need of manually turning on/off the room fan while ...
