Tutorial using AVR Crystal Real Time Clock
In this video tutorial, nerdkits show you how to use the timer interrupts on an ATMega168 chip to make a simple timer. It is possible to make your own reasonably accurate alarm clock, create systems to perform timed automated tasks, or create a multitude of other projects with real time clock in AVR.
