The Seven segment display is the most electronic display using this device the display digits from 0-9. In seven segments has an eight array of LEDs arranged in pattern to display the digits.It looks like a square like the lines are arranged in eight pieces as square shape.

7 segment display generally has ten pin in its package.8 pins as for the leds,middle pin for Common and shorted inside itself.The segments has 2 configurations,such as Common Cathode(CC) and Common Anode(CA).

Project Description:

1. PIC16F877A: The PIC16F877A features 256 bytes of EEPROM data memory , self programming,an lcd display port,2 comparator,8 channels of 10-bit Analog-to-Digital(A/D) converter,2 capture/compare/PWM functions,the synchronous serial port can be configured as either 3-wire Serial peripheral Interface or the 2-wire inter-integrated circuit(I2C) bus and a Universal Asynchronous Receiver Transmitter(USART).These features make it advanced level A/D applications.
2. LCD : A liquid-crystal display is a flat-panel or the other electronically modulated optical device that the light-modulating properties of liquid crystal.LCDs are available to display present words, digits, and seven-segents display.
