# IoT Blocks

The Internet of Things (IoT) connects your devices together through the internet, where data can be shared and exchanged. With built-in Wi-Fi, Codey Rcoky can connect to the internet to realize its IoT functionality, such as obtaining data of the weather. Use IoT blocks to explore cutting-edge stuff with Codey Rocky.
