Learn Morse Code with Arduino

 As a tool for helping to memorise Morse code, 'thegrendel' has designed and built a simple Arduino project to solve the problem nicely. His design is a shield comprising of an LCD module, LED, piezo and simple circuitry that works with the Arduino sketch to display and beep  the Morse characters in order, then randomly once more. The author recommends this as a method to memorise the characters. Here is his project in action:

Although the instructions show making the shield from scratch, you could reproduce this much quicker using our Freetronics Eleven - the Arduino-Uno compatible with low-profile USB socket, onboard prototyping space and easy to view LEDs - and our Freetronics LCD and Keypad shield. It contains a bright 16x2 character LCD module as well as five buttons that are read with only one analogue input:
