This project is for anyone interested in working with ARM micro-controllers and lives within range of the DCF77 signal (sorry US makers). The project is really well documented, and all the schematics and programs are available to download from the site. The end results are a nice looking LCD with time and temperature.
The time and date are received with a DCF77-receiver-module (available i.e. from elv.de and conrad.com, ca. 10 EUR). The DCF77-signal is transmitted from a station near Frankfurt/Main, Germany and can be received all over Europe, North Africa and the Middle-East……In times when the DCF77-signal is not available (i.e. thunder and lightning near transmitter) the RTC of the LPC-controller is used to drive the clock.
