Hi all, I am back again, What I did was to try and put a timer sketch into my rtc sketch and for the life of me I can not figure out why I keep getting the message "not declared in this scope" Here's the sketch
/* the checkStartTime, checkEndTime, turnOnLights, and turnOff Lights are my problems, Any help would greatly be appreciated.
