 This quickstart shows you how to build a sample IoT Plug and Play device application, connect it to your IoT hub, and use the Azure IoT explorer tool to view the telemetry it sends. The sample application is written in Node.js and is included in the Azure IoT device SDK for Node.js. A solution builder can use the Azure IoT explorer tool to understand the capabilities of an IoT Plug and Play device without the need to view any device code.
