In this chapter, we start by exploring Raspberry Pi-specific libraries for Python. We will demonstrate these with a few examples by using the Raspberry Pi camera module and Pibrella HAT. We will try a few coding examples with the Sense Hat emulator before moving on to designing a physical circuit using the Fritzing program. Using a breadboard, we will set up this circuit and connect it to our Raspberry Pi.
We will finish off this chapter by building a Morse code generator that transmits weather data in Morse code from the class we created in Chapter 2, Writing Python Programs Using Raspberry Pi. This chapter should take an afternoon to complete.
