**WHAT IS INTERNET OF THINGS?**
The Internet of Things (IoT) refers to the network of physical objects ("things") embedded with sensors, software, and other technologies that enable them to connect and exchange data with other devices and systems over the internet. These connected devices can range from simple household appliances to complex industrial machinery.

**WHAT IS RASPBERRY PI SIMULATOR?**
A Raspberry Pi Simulator is a software tool that emulates the behavior of a Raspberry Pi computer on a different hardware platform, such as a regular desktop or laptop computer. It allows developers to test and run Raspberry Pi applications and projects without needing physical Raspberry Pi hardware.

Creating an IoT (Internet of Things) solution on Azure involves several steps, including setting up IoT Hub, registering devices, sending telemetry data, and processing data. Here's a step-by-step guide

**STEP: 1**
Create an Azure Account at https://azure.microsoft.com/ and login to Azure Portal (https://portal.azure.com/)

Click on "Create a resource" and search for "IoT Hub"

**STEP 2** Paste the “primary connection string" copied from **STEP 9**  from the IOT device portal on Azure into “Line 15” on the Raspberry PI Simulator and click on RUN.
Raspberry Pi Simulator will starts blinking Red flashy Red Light, communicating to the IOT Device in Microsoft Azure portal and recording data and messages as seen below
