GitHub - TaqwaHamed/Calculator: It is a simple calculator which is responsible to do four basic operations (addition, subtraction, multiplication and reminder) on two operands or more than two , and each operand consists of one digit or more. the maximum length of the operand is 15 bit in length and we will handle the precedence of the operations . The calculator also support to change the entered operation by re-entering the new one (as the computer calculator application).The Hardware required to carry out this project based on ATmega32 (8-bit microcontroller), LCD, Keypad and we are going to use stack data structure and infix-to-postfix algorithm to handle the operations precedence (that’s the way how computer performs the mathematical calculations). This calculator is based on microcontroller for easy and speedy calculations .The Microcontroller ATMEGA32 is programmed with C-programming language and compiled using AVR GCC using eclipse IDE and proteus simulation software.
