This step-by-step tutorial contains everything you need, not only to survive that first contact, but also to learn to enjoy Code and actually do it well. Even if you detested learning it in the first place

This tutorial will show you how to connect a Morse key to the Raspberry Pi GPIO pins, and how to write code to play tones when you hold the key down. You will also decode the Morse that you're keying so that it comes up on the screen.

A low-cost Arduino project expanding on the button tutorial, where three inputs act as "buttons" generating Morse code on a WOTDUINO. This keyer, costing around £4, offers learning potential and hints at more complex ham radio applications.
