This experiment uses the same oscillator circuit as used in the previous experiments. Here, a switch is used to form a telegraph. Telegraph's where widely used in the last half the the 19th century before telephone systems. Telegraph's have only two states on and off. A code called Morse Code was developed by Samuel F. B. Morse of dots and dashes (long or short transmission burst) to send message in the form of electrical current along wires for communication.
