The system combined with an android mobile platform and a small 2-wheeler that is under control. The mobile platform requests to connect to the small car and then sends instructions to control it by calling the Android system of the Bluetooth API. The small car is made up of 2 step motors with their drivers and main MCU chip, connects with and accepts instructions from Android mobile platform through the BT module, meanwhile, the status information is sent to the application software. Nowadays smartphones are becoming more powerful with enhanced processors, greater storage capacities, a richer entertainment function and more communication methods. Smartphone, which is a small but powerful device is rapidly changing the traditional forms of human-machine interaction. Users of smartphones, smartphones have gradually become a portable device for multiple use and provided people for their daily use. In recent years, an open source Android platform has been widely used in smart phones. Android has a complete software package consisting of an operating system, middleware layer and main applications. Unlike other existing platforms like iPhone OS, it comes with Software Development Kit (SDK), which provides essential tools and applications. DC motors are widely used for variable speed drive systems in industrial applications such as industrial automation, electric drive, aircraft, military equipment, hard drives due to their high efficiency, quiet operation, compact, reliability and low maintenance .
Due to the advancement of wireless technology, several connections are introduced as GSM, Wi-Fi, ZIGBEE and Bluetooth. Each of the connections has its own specifications and applications. Among these wireless connections, Bluetooth technology is often implemented. Bluetooth is mainly used for data exchange. Adds new features to smartphones. The Bluetooth technology was created by the telecommunications provider Ericsson in 1994, shows its advantage when integrating with smartphones. It has changed the way people use the digital device in their home or office, and it has also transferred the traditional digital wired devices to wireless devices. A Bluetooth host device is capable of communicating with up to seven Bluetooth modules at the same time through a link. Considering its normal working area of less than eight meters, it is especially very useful in the domestic environment. Speed control was implemented using Bluetooth technology to provide communication access from the smartphone. Communication plays an important role in today's daily life and can be used as a better tool in the control system. It handles wireless communication and is used to control the direction of motor movement.
