DIY Telegraph

Morse code is one of the most known codes in the world. Here's how to make an inexpensive telegraph to send messages in code. I did this for a science project. I got a low mark cause it dosen't qualify as a "simple machine". I hope it goes to better use out here.

I. Connect the negative wire of the battery to the negative wire of the buzzer

If you want to chat to someone with a telegraph, make another one and connect the buzzers with a long wire. Then when you type a message your buzzer and the buzzer at the other telegraph will make the same message.
