    Thanks you for your quick reply! :-)I'm going to give it a try :-)I read in a previous post that you have updated the code and plan on having it on a private blog. Is the blog operational or do you happen to have the updated code available on a different page?

    I really like the logging function, it was what I was looking for but I noticed that the code is writing to the EEPROM. I don't know if this happens every 15 seconds (my knowledge of programming is limited) but according to Arduino there is a limit of 100.000 read/write before the EEPROM brakes... x 15 sec = 1500000 sec / 60 = 25.000 minutes / 60 = 416 hours (less than 18 days) before the EEPROM is broken according to Arduino as I quote "The EEPROM memory has a specified life of 100,000 write/erase cycles, so you may need to be careful about how often you write to it."Does it write every 15 seconds to the EEPROM or is it once per day to store the time?
