As with Chapter 11, we can continue to generate a diagram on mermaidchart.com, you may see a service flow diagram generated, as shown in the following example.
Figure 12.1 – An internet access diagram
In this diagram, we use the LED D4 on the ESP32 and the buzzer to indicate the status of internet access. They provide visual and auditory signals to easily show whether internet access is successful or not. This method is more convenient than observing printed messages in the TERMINAL window.
In this section, we created an internet access diagram with AI Chat on mermaidchart.com. By following this diagram, we can start to instruct ChatGPT to update the previous code in Chapter 11 to support internet access through Wi-Fi.
