Summary
In this chapter, you learned how to create a sample flow (application) by comparing Node-RED to a real IoT use case. We experienced using the sensor module and Raspberry Pi to exchange data with Node-RED, so we had a feel for IoT.
The flow steps created here will help you create different flows with other sensor modules in the edge device in the future.
In the next chapter, we will use the IoT use case as we did this time, but we will create a practical sample flow (application) on the cloud side (server side).
