The purpose of the project is to build a basic calculator based on microcontroller ATMEGA32. It uses 4×4 matrix keyboard as input device with a 74C922 decoder. This decoder generates an interrupt through External Interrupt INT0 every time a key is pressed. The result of calculation displayed on 16×2 LCD.
MCU firmware is written in C language and is compiled using WinAVR. Basic math calculator project is designed by Jaime Andres Arteaga. Download : source code
