Welcome to Duinoland!
WWVB
WWVB Building Blocks......
The WWVB Arduino clock is built on the JJY60 module from Universal-solder.com.
Using the JJY60 as the time source, an Arduino Uno can be connected to a local display for time, date, and temperature.
The JJY60 receives data from Fort Collins, Colorado. It outputs the time data into serial stream that the Uno can decode and display locally.
The code for Uno is based upon contributions from several authors. See the base code at http://duinolab.blogspot.com/2009/06/arduino-cmmr-6p-60-almost-accurate.html
The original C-Max CMMR-6P-A2 WWVB module is no longer available. That necessitated the change to the JJY60.
Several code changes were made to add "Marker" and "Frame" indications to the display. The photo show the Velleman shield being utilized for the local display.
