I am trying to follow and wire up the circuit given here. The explanation is in this page.

enter image description here

In the circuit, IR1 is the component which has an IR receiver connected to a relay.

  • From my understanding of the circuit, relay is turned ON when the IR receiver receives an IR pulse. Is my understanding correct?

  • I am using an TSOP1738 IR receiver and this relay. How do I connect the receiver to the relay? I understand that relay has two states, normally open and normally closed along with a common terminal. With respect to the circuit shown, which of these should be connected to the IR receiver?
