NO.1 Project Introduction
With the rapid development of modern business automation and retail management, efficient and accurate weighing and pricing devices play an important role in supermarkets, vegetable markets, convenience stores, and other scenarios. To meet the demand for low-cost and high-reliability small-scale weighing, this project designs a digital electronic scale system based on the 51 microcontroller. The system uses the 51 microcontroller as the core controller, combined with a 4×4 matrix keyboard for unit price input and function settings. It collects the analog signals from the weighing sensor through the ADC0832 analog-to-digital conversion chip, achieving precise measurement of product weight, and displays information such as weight, unit price, and total price in real-time on the LCD1602 screen. The system has an automatic calculation function, which can automatically complete the total price calculation based on the actual weight after inputting the unit price, realizing integrated weighing and pricing operations. This design features easy operation, clear display, and rapid response, not only improving transaction efficiency but also reducing the risk of manual calculation errors, making it suitable for small and medium-sized commercial scenarios with strong practicality and promotional value.
NO.2 Project Principle
