The core functionality of the system revolves around the Arduino microcontroller, which serves as the central processing unit. RFID tags are employed for item identification and inventory management, ensuring seamless checkout processes. An LCD display provides real-time feedback to the user regarding scanned items and billing information, enhancing transparency and convenience.

The integration of a DC motor enables autonomous navigation capabilities, allowing the trolley to follow the customer through the store with minimal user input. This functionality is complemented by IR sensors and an SR-04 ultrasonic sensor, which ensure obstacle detection and avoidance, thereby ensuring safe and efficient navigation in crowded store environments.

Overall, the “Follow Me Check-Out Trolley with Billing” project aims to revolutionize the shopping experience by combining advanced technology with everyday retail operations.  This abstract  highlights the innovative use of electronics to streamline shopping cart functionality, improving customer satisfaction and operational efficiency in retail settings.

The GPS is the acronym for Global positioning system. This GPS receiver is capable of identifying the location in which it was present in the form of latitude and longitudes. The GPS gives the data received from the satellites. For this information the GPS communicates with at least three satellites in the space. The GSM modem provides the communication mechanism between the user and the microcontroller system in the form of SMS.

The main controlling device of the project is Arduino. If the vehicle gets any accident; Arduino will send the alert SMS along with vehicle location to the predefine mobile number. then Arduino will activate the buzzer for alerts. The status of the project will display on LCD module.

The main controlling device of the project is arduino which is interfaced to the input and output modules and take the necessary action upon the situation. The Microcontroller is loaded with a program written in embedded ‘C’ language to perform the task.
