Morse code trainer



This is a quick weekend project.  I wanted something that would send random strings of characters in Morse code, grouped into sets of 3 or 4 at at time.  This little box has a power switch, a speaker, a knob for volume, and a knob for sending speed.  It's powered by a 9v battery, and is controlled by an Arduino Nano.  There's really not much else to it except for the code.
