Summary
In this chapter, we discussed interfacing sensors to the General Purpose Input/Output (GPIO) pins of the Pico, turning appliances on/off using a relay box, interfacing LED strips to the Pico, and publishing sensor events to the cloud. We discussed controlling an LED strip using a variant of the Pico, namely, the RP2040 Connect.
The examples discussed in this chapter were primarily chosen as examples that could be discussed as individual weekend projects.
In the next chapter, we will have fun with gardening. See you shortly!
