-<​note>​The project involves building an arithmetic ​calculator. The goal I sought in implementing the calculator was to comprehend how a calculator is constructed. Even if we can currently perform calculations using our phones, there may come a day when we also need a pocket calculator. For this reason, I built my own calculator using an Arduino board.</​note>​+<​note>​The project involves building an arduino ​calculator.

-<​note>​I used an Arduino payload to do mathematical operations and to interface with the keyboard and LCD screen. Thus, I've connected an LCD screen with an I2C interface to the Arduino board. The LCD display is used to display messages, inputted numbers, and calculated results. ​Tastatura ​is used to introduce numerical values and arithmetic operations. After I entered the code on the Arduino shield, I retained it using volatile memory. I connected a 9V battery to the Arduino board using a battery connector and a mufa so that I could use the calculator without a laptop. The user will enter two numeric values and choose the mathematical operation they wish to perform. Once the user presses the button, arduino uno will calculate the result and display it on the lcd screen.</​note>​+<​note>​I used an Arduino payload to do mathematical operations and to interface with the keyboard and LCD screen.

 +Conclusion :
  
 +<​note>​This project gave me the chance to better understand fundamental software and hardware concepts. The fact that I could use a variety of components was helpful in figuring out how they related to one another and how they worked. The majority of the issues were related to connecting the LCD screen. The screen appears at the beginning, but we are unable to read any messages from it. This issue was resolved by adjusting the contrast using the power meter that is located underneath the module. Additionally,​ since I2C was the interface I used, I had to use a program to scan the I2C device I was using in order to obtain its address. With all of them, I was able to complete the project with a functional algebraic calculator.</​note>​
