Prototype System Control Car Garage Based Microcontroller ATMEGA 8535

Abstract

In this study have designed a prototype of a microcontroller-based control car garage ATMEGA 8535. The workings of this car garage can be controlled in three ways. First by using the remote control, both by means of pressing the keypad, the third by using infrared sensors. The first is the use of remote control, remote control that has been made to control the garage door to open and close the car from a maximum distance of 30 meters. The second is the use of control keypad, keypad is used to control the opening and closing car garage in close proximity so that the user can embroider the keypad button corresponding to the data / bits that have been specified. The third is the use of control infrared sensors, infrared sensors can control car garage open and close automatically to the car objects directly.

The remote control as the control system works by encoding the data bits / binary sent and received microcontroller ATMEGA 8535 after passing the lopping on the microcontroller. While the door sensor control system uses an infrared LED and photodiode transceiver as receiver for detecting cars that will exit / entry garage, so when detected car passing through the infrared sensor, the control system will open car garage. In addition to using the remote control system such as control, keypad and infrared sensors, controllers car garage is a password, so that car garage open and close system can still be used even if not using the remote.
