3

Put your circuit in a different room. Repeat all these steps so the person in the other room can silently communicate with you.

4

Print out a Morse Code key if you haven't ever memorized one. if you want, you can grab a writing utensil and paper so you can write down the dots and dashes, so you can translate them after. If you get really good at it, you can just write down the letters as you see the flashes of light.
