## Article

Summary:

Just for the record, the Arduino alone cannot function as a web server. Unlike the Raspberry Pi, which is a fully functioning computer, Arduino requires an Ethernet shield to connect to the internet.

**PREPARING THE HARDWARE**

For this project, we are going to display DHT22 Temperature and Humidity sensor data from an Arduino and an Ethernet shield paired to a web page you can access anywhere in the world. To accomplish that, connect the following components, as shown in Figure 2:

After assembling the components, plug a LAN cable to the RJ45 connector. The other end must be on your router that is connected to the internet.
