CALCULATOR-89c52-microcontroller-with-proteus-simulation

We need to design a calculator using a microcontroller, LCD and a keypad smallcalc. first you need to enter the single-digit number then valid operators and in the last another single-digit number. The PIC Microcontroller will perform the mathematical operation as per the operator on the entered operands. The result will reflect on the LCD. If you will enter anything besides the mentioned steps you will get the warning message.

Definition of the problem: interface between keypad and lcd get average of N numbers given by keybad and display on lcd Project hardware requirement • One 89c52 microcontroller • Bread board or PCB (Making Circuit) • 16×2 lcd (Displaying Text) • 4×4 keypad (Taking Input) • Potentiometer (For setting lcd contrast)
