How it works

     Basically in every remote there will be a circuit board and for each and every button there will be a unique  pulse associated with it . This unique pulse is created due to as the current is running  all over the board and whenever you press the button it triggers the gap and pulse. This pulse is used to identify every button.

This pulse is transmitted through a transmitter which is LED in this case . This led is present infront of controller .  These pulses are transmitted by infrared rays which are not seen by any human or any camera .
