The Arduino library is built from the Azure Embedded SDK for C. For more details about it, please refer to the [official library website](https://github.com/azure/azure-sdk-for-c).
There are several other alternatives to get MCU-based devices connected to Azure. See [Other Azure IoT SDKs](https://learn.microsoft.com/azure/iot-develop/concepts-using-c-sdk-and-embedded-c-sdk) to learn more.
This library package contains the following samples. Please refer to their documentation for setup and execution instructions:
What is the difference between **IoT Hub** and **IoT Central** samples?
1. IoT Hub samples will get devices connected directly to [Azure IoT Hub](https://docs.microsoft.com/en-us/azure/iot-hub/iot-concepts-and-iot-hub)
1. IoT Central samples will leverage DPS ([Device Provisioning Service](https://docs.microsoft.com/en-us/azure/iot-dps/about-iot-dps)) to provision the device and then connect it to [Azure IoT Central](https://docs.microsoft.com/en-us/azure/iot-central/core/overview-iot-central).
Please note that provisioning through DPS is mandatory for IoT Central scenarios, but DPS can also be used for IoT Hub devices as well.
