Controlling relay switches with an infrared remote -Use
* switch * * Each time the input pin goes from LOW to HIGH (e. g. because of a push-button * press), the output pin is toggled from LOW to HIGH or HIGH to LOW. There's * a minimum delay between toggles to debounce the circuit (i. e. to ignore * noise).

Arduino Control Relay Schematic. How does the circuit works. 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 fan) will be powered from the main power supply.
