This activity will be different from others you have done untill now. You were used to follow a block of instructions to build your prototype. This time it will be different. You have to build a telegraph but we won't say you how to do it.
Look up information on the internet and build your own telegraph. You choose your design, materials, and all what you want. Become an inventor and feel as Samuel Morse.
