Hi,
i would like to know what are the other component that can be paired with an Ir Emitter.
Ir Receiver is one, but i also want to know the other since Ir Receiver only response to a specific frequency.
additional:
i would like to make a sensor that will be triggered when someone pass by the hallway.
what would be the components i should use?
