Click and hold the button on the top right to turn on Alarm Set Mode. As soon as you let go of the button, Alarm Set Mode will turn off. While it is on, press the up or down arrow keys to set alarm. No, you don't need to actually use this as an alarm clock, I just thought it would be fun to make.
I did everything : ) (But to be honest it was pretty easy. There wasn't much to do!) Sorry that it doesn't work very well.
