Summary of 8051 CALCULATOR CIRCUIT
This article outlines an 8051-based calculator circuit featuring a keypad and LCD display. The keypad utilizes a matrix of rows and columns where the microcontroller detects pressed buttons by scanning for specific row-column combinations. When a key is pressed, the system identifies it by determining which row and column lines are active, allowing for accurate input processing.
Parts used in the 8051 Calculator:
- 8051 Microcontroller
- Keypad with rows and columns
- LCD Display (2x16)
- Keil source code
- Proteus ISIS simulation files

8051 Calculator Circuit Operation As seen at half one has to use the keypad and an LCD with 8051. The keypad consists of rows and columns. When the button is pressed certain keys combined treatment. Pressing 1, column 1 for example is 1.sat nanny and 1-5 should be combined. More than one button in a column or row is connected primarily to determine which button is pressed first applying to the others which row, column 1 to 0 of 0 value must be determined to reach out button.
