        abstract = {A calculator is a basic digital device that perform arithmetic calculation like addition, multiplication, subtraction and division. With the advancement of microcontroller technology, calculators can be designed using embedded systems to make them more compact, efficient, and cost-effective. The Arduino-based calculator is a simple embedded system that uses an Arduino UNO as the main controller. A 4×4 keypad provides input from user such as entering numbers and arithmetic operators. The calculated results are displayed on a 16×2 LCD display. The Arduino reads the input from the keypad, processes the arithmetic operation based on the operator selected, and then displays the result on the LCD. This project helps in understanding the basic concepts of embedded system design, keypad interfacing, LCD interfacing, and programming using Arduino IDE. It is useful for educational purposes and underlying basis for more advanced digital systems.},
