 Now, you should be able to use the Arduino IoT Cloud nodes from the palette on the left side of the editor. There are five IoT Cloud nodes: property in, property out, historic, periodic, and inject. Each of the nodes has a description of its function, which appears when you hover over the node.

 Now that you have a node pulling data from the Arduino IoT Cloud, you need to use the inject node in order to manipulate and send the data. All you need to do is dragging an inject node and connect it to the property out node, then double clicking on the inject node to ensure that the right Thing and property are selected.

 The next step is adding a **function node** that processes the data coming from the Arduino IoT Cloud. This node is important when working with a constant flow of data, as it allows you to use JavaScript code to create customized triggers from the received values.
