Perancangan Sistem Multi Locker dengan Penyandian Berbasis Mikrokontroler Atmega 8 Menggunakan Android Phone

Abstract

Has designed a multi tool locker with ATmega 8 microcontroller based encryption using android phone. This device consists of a mechanical door locker, stepper motors, android phone, buzzer, and Bluetooth HC-05 that serves to send a password between android phone with a Bluetooth adapter that will be used sebgai control system from near and far. Softwere on this instrument using Bascom AVR programming language. This tool is used to facilitate storage and improve system security storage of goods. The working principle of the circuit in general is the minimum system connected to a voltage source PLN by the adapter, after the system is activated then the downloaded program based on IC microcontroller. The program will accept commands from the user via android phone with Bluetooth network HC-05. The phone sends a password code from the user via android with HC-05 Bluetooth module as an intermediary by the microcontroller. If the password is correct microcontroller will drive the motor to open or lock locker.
