Throughout the text, we have presented projects that demonstrated a wide variety of coding techniques and asked you to make modifications to gain a greater understanding of the programming process. In this capstone chapter, we present projects that are fairly difficult and require you to improvise solutions to produce a fully functioning project. This first capstone section asks you to build a reader that will respond to the last project presented in Chapter 9. The electronic circuit and corresponding Arduino code will read the Morse code to some extent. The code as given will respond to the slow (default) code speed, and to the audio frequency of 2 kHz sent to a small speaker.
