# Arduino Web controlled switch/relay over WiFi using arduino Ethernet shield

> Arduino Web controlled switch/relay over WiFi using arduino Ethernet shield

Original author: losel (source: https://www.engineersgarage.com/arduino-ethernet-shield-controlled-switch/)

## Components

- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))

## Article

Now lets put all the above in practical form and switch On/Off a fan using arduino uno and arduino Ethernet shield. We will connect our arduino with our home network and try to toggle arduino gpio(general purpose input output pin) using our laptop, cell phone or computer.
