This project is a dialer box that connects to the phone and can be used to store and dial phone numbers, pins, and credit card numbers. The project uses PIC 16F690 microcontroller and a NTE1690 DTMF dialer chip.
Because this is an IP phone and I cannot just send the DTMF tones over the line, [...]

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.
