Abstract : This paper focused on design and implementation of a microcontroller based calculator which will perform simple arithmetic using a calculator keypad and a 16x2 Liquid Crystal Display (LCD). The program is limited to single digit input and double-digit results. This allows the program for the arithmetic operations to be simple, while the same principles can be extended to multi-digit calculations.
