How did the schilling telegraph work?

The Schilling telegraph, developed in the 19th century, was an early electrical telegraph system that transmitted messages using a series of electrical impulses. It utilized a circuit that included a sending key and a receiver, where the sender would tap out messages in Morse Code. The electrical signals would activate a mechanism at the receiving end, producing marks on a moving tape or activating a sounder to convey the message. This system allowed for rapid long-distance communication, revolutionizing how information was exchanged.
