Project Description


This guide is just the tip of the ice berg to build a complete home automation project using Arduino. We will build a Ethernet controlled home automation to control 3 LED’s or switches in your room.

Hardware Required:

• Arduino Uno R3

• Ethernet shield  w5100

• Led’s

• Relay

• Temperature Sensor LM-35

• Light Dependent Resistor (LDR)


  • LED’s : Digital Pin’s 4,5,6
  • LM35 : Analog Pin 2
  • Light Dependent Resistor : Analog Pin 3
