NOTE: This Instructable is currently incomplete. I will finish it before September 19.
I started this project after seeing Nick Johnson's Turing Alarm clock. I found that the PIC chip he used was a little too advanced for me, so I decided to use the Arduino microcontroller. The original project by Nick Johnson can be found on his blog here
. All credits for the idea goes to Nick.
The turing alarm forces you to solve math problems when you wake up. If you get the math problem correct, the alarm stops, and if you don't, you will have to solve another one. My version also includes a 12V light dimmer using a MOSFET. A DS1307 real time clock (RTC) keeps track of the time and the menus are controlled with five buttons.
