1. Project Description

The author for this project states that using an Ethernet shield along with Arduino board users can turn it into a simple web server which can be accessed by anyone on the internet, and by accessing that server with a browser running on any computer connected to the same network as the Arduino board, users can:

• Control hardware from the webpage like fan or lights (using Javascript buttons).
• Read the state of a switch which can be either ON or OFF (using simple HTML).
• Read value of a sensors connected to Arduino board (using simple HTML).

2. Parts

Arduino and Arduino Ethernet shield – To connect with LAN
DC Voltage of 5V from Arduino – To power the Ethernet Shield
Connection speed: 10/100Mb – For optimum performance.
Connection with Arduino on SPI port

Components required:

• 1 x Ethernet cable
• 1 x Wi-Fi Router (Optional)
• 1 x Arduino Mega2560 or Arduino UNO
• 1 x Ethernet Shield
• 1 x Breadboard or blank circuit board can do as well
• 3 x Jumper Wires
• 1 x 1k Resistor
• 2 x 9V DC Adaptor
• 1 x Push button
