Hi, I guess not all I/O ports are used with an LCD shield in place, but all of them are covered. Are the unused pins the open spots on the LCD shield on (for example) the top right, see picture? cheers, Arthur [Picture 2.jpg]

Thanks for the WWVB information. I was wondering why there were not very many projects for WWVB RTCs.
