It has been a while in the making, mainly collecting dust, but I finally finished the project. It is a math alarm clock that prompts the user a math problem which they have to solve to be able to snooze. I got the idea back in college from a blog post from Nick Johnson: http://www.cheaphack.net/2008/01/turing-alarm-clock.html
Attached is the code. I am sure there are a great number of improvements but I am happy for now with ‘operational’. If you have any comments or thoughts on the code or comments in general I’d be happy to hear them.
I used the Ardiuno pro mini, lcd display, voltage regulator, adafruit RTC, and a speaker from a toy phone. In the pic I was programming it with a Deumilanove. I mounted the clock in a butter dish for a container. (walked around in the dollar store forever before I decided that was the best thing.)
