INT0. On the software side create sleep mode for Arduino and use a timer base interrupts which would internally be essentially triggering awakening function and not relay on any external hardware.
Arduino Pin Turns On Transistor>>Transistor Turns On Relay>>Relay Connects Appliance To 120V Power Outlet. With that out of the way, you should also use a resistor to connect your Arduino to the transistor. This prevents the transistor from drawing excessive amounts of current and burning it ...
The way the relay is used, is thus: if you want the relay to turn something off when signalling it from the Arduino, you must connect your application's power source - in this case the battery for our LED - to the normally opened (NO) pin. If on the other hand you want to use ...
The schematic for the full circuits. Here a reed relay (switch) MEDER DIP05-1A57-BV350 is used to isolate the Arduino microprocessor from the flash trigger. The reed switch is not super-fast but it is inexpensive and easy for students to start out with as they are learning. Faster...

Because this just writes the output state of a pin, you could also use this for remotely controlling any digital (on/off) device with a transistor or relay: DC motors, buzzers, oil slicks, control surfaces, etc. Reading a Multi-Position Switch Many RC controllers, particularly advanced ones...
