Bricklett Morse generator.

So my cubs last night did a James Bond themed evening with various code breaking opportunities. Useing My raspberry pi tablet i used https://www.cl.cam.ac.uk/ Morse code program to flash an led. Some work after cubs made the following program that beeps a buzzer and writes out the dash and dots on the screen.
