Summary
In this chapter, we discussed retrieving air quality data from publicly available data sources. We also discussed interfacing a CO2 sensor to the Raspberry Pi Pico to build a dashboard that tracks air quality. Then, we discussed controlling a stepper motor using the Pico, which can be used to point at one among six different categories of air quality. This enables us to build a display that keeps track of air quality in our community.
In the next chapter, we are going to have fun with radios! Join us in the adventure.
