Arduino Calculator with Keypad 4x4 and LCD Display This project is an Arduino-based calculator that uses a 4x4 keypad for input and an I2C LCD for output. The calculator can perform basic arithmetic ...

The background project for this code could be a simple calculator using an Arduino 3.2" TFT LCD Touch Screen. The touch screen would have buttons that perform basic arithmetic operations such as ...

Making projects using Arduino Uno as a microcontroller board is really fun if you are working on Embedded projects. If you want to make a simple calculator that is able to perform all the basic ...

We propose to make a little calculator realising the four basic arithmetical operations using one Arduino and a Nextion touch display. This calculator uses the Reverse Polish Notation, which may ...

LCDs are widely used in applications like token-display machines in s malls and supermarkets, order number displays in restaurants and café, and so on. The project presented here demonstrates the ...

In this article we discussed about 16x2 LCD, its working, pinout, and also how to use 16x2 LCD with Arduino. We provided Circuit Diagram, Complete Arduino Code, and step-by-step guide.
