Abstract

This project explains the development of a basic calculator using a PIC microcontroller and an LCD (Liquid Crystal Display) as the display. This project can be self-operational in controlling the operation of the input and output device used. The input device used is a 4x4 keypad and the output device used is the LCD display. A program is written using C language by using the MPLAB IDE Environment. The program is then assembled to be connected into a hexadecimal file and downloaded into the PIC microcontroller. This project is able to analyze data from the press keypad through microcontroller and display it at LCD display. The functionality is implemented in software (MPLAB IDE). The work that will be done includes development of PIC circuit, software for PIC to taking input from keypad for calculation and displayed it to LCD display. The project executes simple calculation and the result is displayed on the LCD.
