This is a very simple demo video on my project. My project is about DIY Temperature-Controlled Automatic Fan by using arduino UNO. When the temperature reaches above 35 degree celsius, the relay is triggered to be ON and the DC fan will ON. It will remain ON if the temperature is above 35 degree celsius. Meanwhile, when the temperature drops to 35 or below 35 degree celsius, then the relay will OFF and DC fan will OFF.
