Arduino and Morse Code

I got an Arduino to tinker with over winter break, and one of the ideas I had was to write a decoder for Morse Code (video below).

I ended up with a hacked-together bit of code that can decode Morse in real-time, and display in on an LCD.

Parts list:

• Arduino
• LCD
• Push Button
• 10K Resistor (pulldown)
• Jumper Wires
• Breadboard

I followed these instructions for wiring up the LCD (though I did change which pins I used).

My code is available on GitHub.

I even (temporarily) got my hands on a vintage telegraph key, and got it wired up!

My cousin trying it out!
