🔸4 switches- three switches would be placed on the opposing wood board and labeled one, two, and three to the corresponding lightbulbs, and would be switched to form a letter on the other board; the the fourth switch was placed on the board having the lights so that way when the message is received the switch would be flipped as an indicator to those on the other side that the message was received
