BICYCLE LOCK MODEL with ATmega8 microcontroller

This final project aims to create a system that serves as a security device on a bicycle. This bicycle lock model based Microcontroller ATmega 8/8L that serves as the central data processing and system control center. \n The method used in building models of bicycle lock this ATmega8 microcontroller-based design method that consists of several stages: (1) Identification of Needs, (2) Needs Analysis, (3) The design of the hardware, namely: two batteries with the specification 9 Volt that serves as a source of \n power supply, two ATmega8 AVR microcontroller as a recipient of the signal emitted by the remote system and ATmega8L as transmitters are used for the remote control system, using infrared and photodiode as the media sender and recipient data, a servo motor that serves as drive lever lock, a buzzer as the sound source, using a touch sensor IC 555, USART communication between the microcontroller to control the movement of the servo motor and control the buzzer, akrelik and aluminum in the manufacture of model / prototype, (4) software, including: CodeVision AVR, (5) Preparation and (6) testing, in order to get a bicycle lock model based on microcontroller ATmega8. \n T he result of the design and manufacture of bicycle lock model based on ATmega8 microcontroller is able to work well. The performance of this tool was observed by the ability of a tool to unlock / lock the lock lever when given input from the remote circuit, and the buzzer to sound when a touch sensor circuit to get the input of a touch. To turn off the buzzer sound is done by pressing one button of the remote control.
