Morse code transmitter – flash messages to friends with an LED connected to a Raspberry Pi #piday #raspberrypi
Type out a message and this project will convert it to morse code and flash it in LEDs. The project is an update for one originally created for Issue 144 of MagPi, from Sean McManus:
Morse code is a way of sending messages using patterns of lights or sounds. Each letter and number is encoded using dots and dashes. A dot represents a short flash or sound, and a dash represents a long dash or sound (three times the length of a dot).
For issue 144 of The MagPi I wrote an introductory electronics tutorial. It shows you how to connect your first LED to a Raspberry Pi, and gives you the code to make it flash. To make the program a bit more useful, I turned it into a Morse code transmitter.
