Timer Control: The system tracks time using the millis () function, which provides the number of milliseconds since the Arduino started. If the relay is OFF, it checks whether the specified ON ...

Intro One of the most useful things you can do with an Arduino is control higher voltage (120-240V) devices like pumps, fans, lights, heaters etc. Since the Arduino operates at 5V it can’t control ...

When the button is pressed the Arduino board will put pin 2 in HIGH state, meaning 5V on pin 2. This voltage is used to drive the transistor that will switch ON the relay and the load (in our case the ...
