Futsal Field Automatic Alarm Using the Microcontroller at Mega 8535

Now it is growing, sport in the eyes of the community that makes many people try, namely renting out the Futsal field. They are increasingly competing to make their Futsal field business more attractive and more modern Therefore we need a system that aims to set automatic alarms on the futsal field so that there is no need to remind players or visitors and futsal field users by pressing the alarm manually. Because until now there are several places that still depend on regular hours and sometimes always keep the time so as not to miss the time ordered from the customer, therefore we have a goal to build an alarm that automatically uses the ATMega 8535 microcontroller. In this final project we designing and making an Automatic Alarm device Using the ATMega 8535 Microcontroller. Where this tool functions by setting an automatic alarm by using a timer. The hardware manufacture in the form of a mechanical conveyor that uses ATMega 8535. While the ATMega 8535 Microcontroller as a control will sound an automatic alarm. Which will not depend on the controlled time manually, but a device designed using an ATMega 8535 microcontroller which will automatically support the futsal field
