First, log in to your Simuli account and navigate to the Simuli Virtual Lab. Here we will create a new emulated instance of the Arduino Uno. Click on the Launch button under the Arduino to get started.

This will open the configuration menu. First, provide a name for the project. Then, we will add the W5500 Ethernet Module by selecting it from the list of available components. Finally, review that the name for the project and the selected sensors are correct and click on the Launch button.

Once we have clicked on the Launch button, a new instance of the Arduino Uno will be created. It can take a few minutes, so be patient.
If you have not set up your Arduino IDE, follow the guide linked below.
Prerequisites for Arduino Development
Once you have the Arduino IDE ready to go, copy the code given below and paste it in the IDE.

#include <Ethernet.h>

Copied!
Now save the sketch in a folder and keep a note of that folder. We now need to get the compiled binaries for the sketch. Go to Sketch and find Export Compiled Binary. The program will take some time to compile. Once the compilation is complete, go back to IoTIFY Virtual Lab and open the instance we created.
On opening the instance, a new tab will open and we can interact with our Arduino. First, we need to uploadour compiled binary. Click on the Arduino board, this will open a file explorer, navigate to where you had stored the Arduino sketch. In the same folder, a file called sketch.ino.standard.hex will be present (where sketch is the name of the Arduino sketch). Select this file and click on open. Now the hex file will be uploaded. Finally, reset the Arduino so that it loads the new file. To reset, just click the red power button above the top left corner of the Arduino.
You will see that the Arduino will try to connect to Google and send a GET request. Once it connects to the server successfully, we will receive the results.

We have successfully connected to an external server with the Arduino Uno. Now you can try to ping different websites. Keep building and have fun! 🎉
