ABSTRACT Time notification technology is not foreign in our education , especially in the school environment . Application time notification is a means to inform the residents of the campus when lessons or hours of work will begin and end . Generally notification while on a human to ring it . Schools still rarely use automatic notification time can work alone ring the notification time according to the schedule and time available . Working process of this tool is to do with setting the schedule and the time is now , then wait until the application automatically reads the notification time . After the microcontroller will read the data notification list today is already stored repeatedly . In the event of a data match the hours and minutes of time now with today's notification list microcontroller will send a command to connect the switch to the ISD2560 ISD2560 so round the notification reads . This tool is equipped with a 3x4 keypad button that serves as the edit button and input the data and time schedules , but it is also equipped with a series of LCD function display data clock now so that helps users know the hours of the time now . From the research results obtained ISD2560 can connect automatically with notification round , where complete control is at order placement microcontroller ATMEGA8535 with a predefined time . Keywords : notification time , ATMEGA8535 Microcontroller , RTC DS1307 .
