This project implements a simple calculator using an Arduino, an LCD, and serial input. It supports basic arithmetic operations (+, -, *, /, ^) and handles division by zero gracefully. Connect the LCD ...

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 operations such as addition, subtraction, ...

One of [Kale_3D]’s teachers had made an Arduino-powered calculator. It wasn’t robust and didn’t last too long in the classroom environment. After the non-functional calculator sat around the class for ...

All by itself, a calculator based on an Arduino isn’t necessarily very novel. However, [Danko Bertović] of Volos Projects has a nice board that, of course, looks like a calculator. There are 16 keys ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...
