Summary
In this chapter, you've learned how to use each major node in the Node-RED flow editor. You have successfully made your Node-RED flows! The flow steps you've created here are most of the steps you will need to do to create various flows in the future.
The important point learned in this chapter is that each node has its own unique features. By combining these like a puzzle, we can create an application similar to one made through regular programming just by creating a flow.
In the next chapter, let's create a more practical sample flow (application) for IoT edge devices.
