Build a Calculator with Arduino UNO
You find the Arduino program of calculator in this link : https://www.robotique.site/tutorial/b...
The objective of this project is to design and build an electronic calculator using the Arduino UNO board, a 4×4 matrix keypad, and an LCD I2C screen.
This calculator allows the user to enter numbers and select mathematical operations using the keypad, while the LCD screen displays the entered data and the calculation results in real time.
This project helps learners understand how to interface input devices (keypad) and output devices (LCD display) with a microcontroller. It also introduces fundamental programming concepts such as data input, processing, and output.
By completing this project, students will gain practical experience in electronics, embedded systems, and Arduino programming, and will learn how to create a functional and interactive embedded application.
