Perancangan Alat Membuka dan Menutup Gerbang Berbasis Mikrokontroler Atmega8 Menggunakan Ponsel Android Via Bluetooth

Abstract

Has designed a tool controlling and securing the gate using mikrokontroler ATmega8. This tool consists of the sensor limit switch as the sensor limits, infrared to prevent collision course between the object was traffic against the gate. Bluetooth HC-05 as receiver command and continue to mikrokontroler ATmega8, motor DC as a mechanic movers, and driver L293D as the regulator the turn of the motor. The principle of a series of it is generally minimum system connected to the source of elektric PLN using adater. After the system active then connected between bluetooth android with bluetooth adabter HC-05, after connected then user will give a command through android and will accepted by bluetooth HC-05 and passed to ATmega8 and verification in accoredance with the program for opened and closed gate. And will be detected by sensor limit switch when the gate was touched the line to closed and opened and will give command to mikrokontroler to stop motor, and infrared to detect the object that has not been through and will stop a motor as closed.
