Arduino Clock

I spent part of yesterday and today assembling this monster of a digital clock. The brains behind it, like my previous project, is a Dallas RTC chip; the rest is just microcontroller glue to read the time over the bus and write the hours and minutes to a quartet of seven segment decoders. The arduino microcontroller board can run off of a 9V battery so this assembly is portable, like the, er, $0.50 worth of electronics that are in your wristwatch.

Angeline had a good question for which I didn’t have an entirely satisfactory answer: “Why?”
