74HC595N IC Shift register

Many of us face problem when try to connect more sensors and output devices in arduino. Because there is no enough ports to connect.To overcome this some may go to arduino Mega.We need not go to Arduino Mega to have extended ports.Here is a solution to extend the ports of Arduino Uno. We extend the ports of arduino using IC 74HC595N which is ashift Register for Serial in and Parallel out.This register IC takes 3 pin input and gives output at 8 Pins. Thus this extends 3 pins to 8 pins.The extended pins are used only as output port to connect output devices such as LED,LCD,Bar Graph Display,Piezo Buzzer etc.
