Abstract

• The “Reverse Moving Control System” is mainly implemented by using Arduino UNO microcontroller board and ultrasonic sensor (HC-SR04). The peripheral components are liquid crystal display (LCD), light emitting diodes (LEDs), piezo buzzer and Bluetooth wireless module (HC-06). The ultrasonic sensor transmits and receives the signals from the obstacles near the automobile. The signal is then sent to the UNO board which is the main controller of the whole system. The distance between the automobile and the obstacle is calculated by Arduino IDE software. The output data is sent to piezo buzzer, LCD and LEDs. Bluetooth module is used to control the moving of automobile in back and forth direction. It is a connection module between automobile and android mobile phone. This device intends to protect the automobiles from accidents during parking. It can also be modified as a backup camera in modern cars.
