Summary
In this chapter, we discussed interfacing two Pico boards via the UART interface and interfacing sensors via the I2C interface because they will come in handy in the projects that we are going to discuss in the upcoming chapters. The examples discussed in this chapter should help you to interface peripherals for your projects since we discussed the most used communication interfaces.
In the next chapter, we are going to discuss home automation and using the Pico in controlling appliances. You will notice that the complexity of projects increases with every chapter.
