Intelligent Remote Control Car Based on the Bluetooth of Android Mobile Phone

Abstract

With the development of technology, the rise of the internet promotes the rapid progress of android’s smart phone, and with its unique advantage of openness providing more high quality convenient technological achievements for us. Remote control technology is more and more widely used in people's daily life, a variety of remote control car on the market emerge in an endless stream, but due to the small car generally has their own remote control, they can’t avoid strain of long life, limitations and the matching problem of model, with the help of the more and more popular android platform, this design uses bluetooth transmission technology to improve and re-innovation the remote control car.

This design consists of the smallest system of STC89C52 SCM, motor drive circuit module, SPP-CA bluetooth module, direction indicator module, alarm module and power module. Through the matching of cell phones and bluetooth module, real-time bluetooth reception is achieved. MCU sends command signal by using the L293D motor driver chip to control car corresponding action, such as moving forward and back, acceleration and deceleration, left-handed rotation and right-handed rotation, etc. The designed intelligent remote control car is easy to operate, and has the feature of flexible, high control stability, high cost performance. The design provides high application value as well as a certain reference significance for the future smart home design.
