How to build a simple digital alarm clock with an LED display and a lot of useful functions. It has an alarm which can time out, a stopwatch, a countdown (kitchen timer), it shows the date and day of the week, it works with leap years and summer time (daylight saving time) and the speed can be digitally corrected from -120 to +120 ppm in 1ppm steps to make it very accurate. It runs on 5V and it uses ATmega16A Atmel AVR.
