Arduino Based Smart Phone Controlled Robot Car

The subject of robotics and automation has undergone a revolution in recent years due to the integration of smartphones with microcontroller-based devices. The creation of an Arduino-based robot automobile that can be operated by a smartphone using Bluetooth is the main goal of this project. The main goal is to create an affordable, easy-to-use robot car that can be commanded remotely and precisely navigate a variety of situations. Using a ULN2003 stepper motor driver and stepper motors, the system uses an Arduino Uno microcontroller to execute commands from a Bluetooth module (HC-05/06) and regulate the robot's movement. The Arduino understands and responds to directional commands sent by the smartphone, which serves as the user interface. The wireless control of robotic systems is demonstrated in this study, which also lays the groundwork for more sophisticated uses including home automation, surveillance robots, and driverless cars. Because of its exceptional responsiveness, low latency, and precise control, the robot car is perfect for DIY projects, education, and prototyping. The straightforward design and efficient operation demonstrate how cellphones and microcontrollers may be combined to create intelligent robotic systems.
