ok i pasted it into my ardino oo23. when i try to verify or upload i get the following message/*
// ATMEG328P-AU Microcontroller LED lighting controller for aquarium use.
// The programming code uses a DS1307 Real Time clock to set the LED lighting schedule. Current date and time can be accessed with the serial monitor set to 9600 baud.
// sunrise/sunset time,length of fade duration, and the length of the day are selectable via the programmed schedule.
// Circuit description
// PWM pins described below connected to dimming circuits on drivers spread among 6 seperate channels.

delay(1000);

all that is in red under a message that says RTC was not declared in this scope . what am i doing wrong? thanks again for the help.
