Now all you have to do is make i fit on your wrist.

Just one question why did you use LED's over LCD's?

LCD's are more fun to play with!

Well my group and I only had CC (Common Cathode) or CA (Common Anode) LEDs available to us at our labs. The LEDs are easy to work with, and they require no multiplexing. You can directly take the outputs of 4511 CMOS (BCD to Seven Segment Display) into the inputs (a through g) of the LED. We originally were going to have a 4 seven segment display but that required multiplexing, and a couple of other things we couldn't get working before the end of the semester.
