Arduino 004: Morse Code Beacon
This will help you:
Create a light that delivers a message in Morse code when a button is held down
This activity is taken from a scavenger hunt I completed once at Olin. Someone had removed a light switch cover and installed an Arduino running a similar program behind it. When you used the light switch in the right way, the program would be triggered to flash out the message required for the next step.
If you feel like going further, you can instead have it flash out a message typed into the serial monitor.
