Hi all. Total moron here lol. Not into electronics but I'm a Magician and am creating a new effect that uses a 2ch wireless relay switch with remote. I ordered the Relay switch and have attached pics. My main issue is that you need to add the transmitter by using the set learning dots as in the Pic. Anyone give me a clue how I go about this? I assume I need to power it but just not sure. Any advise well received. Thank you.
