This is the second Arduino project by Daniel.He writes:
Yesterday I was going to start watching a movie, when me and my friend pedro decided to give up on the movie and build a binary clock. After sometime thinking on how to program it, we made it. It works beautifully, so I decided to show here how Iโve done. It may not be the easiest way to make it work, but thatโs what weโve done.

The system works like this. WWVB is the call sign of the atomic clock in Colorado. It transmits at a very low frequency, 60kHz. This allows the signal to travel far, but requires a sensitive receiver to pick it up. Then the signal must be decoded. In most areas, one cannot get reception all the time. [more]
With this digital DCF77 clock with LCD and gong,you always get the right time and date.This project make use of a PIC16F628(A) and a DCF77 receiver.The DCF77 is a longwave time signal and standard-frequency radio station. Its primary and backup transmitter are located in Mainflingen, about 25 km south-east of Frankfurt, Germany. It is operated by T-Systems Media Broadcast, a subsidiary of Deutsche Telekom AG, on behalf of the Physikalisch-Technische Bundesanstalt, Germanyโs national physics laboratory. DCF77 has been in service as a standard-frequency station since 1959; date and time information was added in 1973.[more]
Here is a simple PIC16F84A alarm clock. This page summarizes this discussion (in french) in my forum, where Samir (aka numerique1) requested for help to build a weekly alarm clock for his school. Many thanks to him for his tests and patience.This clock counts seconds, minutes, hours and day of the week.Time is displayed on 4 seven segment LED displays.[more]
This is LCD Clock/Calendar based on PIC16F628.Time and date are displayed on LCD 1×16 in format HH:MM:SSx mmm dd, where: HH = Hours MM = Minutes SS = Seconds x = AM/PM mmm = Month (Jan, Feb, Mar) dd = Day.[more]
