ABSTRACT

The STC89C52RC microcontroller serves as the core component, while a 4x5 matrix keyboard is utilized for data input. An LCD1602 display is employed for data visualization, and time processing is managed by the DS1302 chip. Additionally, the DS18B20 chip is responsible for measuring the ambient temperature. The multi-functional calculator is a basic arithmetic tool for addition, subtraction, multiplication and division, and it can also be used to time the year, month, day, hour, minute and second, as well as measure the current ambient temperature through its time and temperature measurement chips, bringing great convenience to users.

KEYWORDS
