Function of Calculator
It can be used as a Calculator. This is a basic tool for performing mathematical calculations, allowing users to input numbers and operations on a display module. The interface features buttons for numbers, operators, and functions. Users tap on these buttons to input numbers and operators, which are then processed by a microcontroller.
The calculated result is displayed on the screen. A modular design can implement the calculator function using a dedicated calculator chip, a general-purpose microcontroller, or pre-existing software libraries. This versatile device can handle various tasks, from simple arithmetic to complex calculations.
