Once he returned home he began drawing the plans for his electrical telegraph. His first model was composed of a wooden frame, which would hold an electromagnet, paper, and a marking pencil suspended from a pendulum. The pencil would mark on the paper as the electric circuit was opened and closed. What is now known today as Morse code is what Samuel Morse created when he used dots and dashes in his telegraph. To continue his experiments and research he needed financial support. Fortunately, Morse was joined by Alfred Vail, the son of a wealthy business owner and skilled mechanic.
