This paper aims to design an Android interface, an Arduino bot, and write a program on the Arduino microprocessor. Arduino cars contain Arduino microcontrollers with basic mobility features. Arduino programs contain instructions for mediating between an Android controller and an Arduino car. Android mobile controllers use different mobile sensors to supervise motion. An appropriate program in the Arduino microprocessor to interact with the Android controller has to be created. The program has been successfully compiled through the Arduino IDE on the Arduino microprocessor and loaded into it after proper checking of the logic to decrease any loss or damage to the hardware. An Android application is created that provides the user with an interface to interact with the Arduino-powered car. The interface is easy to use and provides feedback from the Arduino microprocessor through Bluetooth after giving instructions to the Arduino for various actions through the interface. The Android application is to be created with the help of Android Studio, which provides more capability and stability. After doing all of this, the application is thoroughly tested, and the maximum number of errors and wrong logic in the microprocessor program are found.
