Design Project: Telegraph System
Modify your telegraph station design to incorporate two indicator lights: one for transmission and one for reception. How could the stations circuitry be changed such that there would be separate lights to indicate different directions of data travel?
Challenge: modify the circuit so that the “sending” light only illuminates if the other station’s “receive” light actually has a complete circuit. In other words, if the receiving station’s “receive” light fails open and does not light, the transmitting station’s “send” light should not light either!
