====Objective====
To connect 2 raspberry pis and send morse code form one and display on the other
====Prerequisites====
 raspberry pie,monitor, keyboard, data cable, hdmi to usb cable, network cable

====Background====
The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools.[7][8][9][10][11]

The Raspberry Pi is manufactured through licensed manufacturing deals with Newark element14 (Premier Farnell), RS Components and Egoman. All of these companies sell the Raspberry Pi online.[12] Egoman produces a version for distribution solely in China and Taiwan, which can be distinguished from other Pis by their red coloring and lack of FCC/CE marks. The hardware is the same across all manufacturers.
