Producing Music and Speech

In the previous chapter, we learned how to work with NeoPixel rings and strips. We also explored how to program the MAX7219-based 7-segment 8-digit display board. We worked with an external MicroPython library for the MAX7219 project and now we are comfortable working with external libraries. We created interesting projects with these cool external displays.

This chapter will explore a new dimension of the Micro:bit by discussing various methods of generating music and speech using Micro:bit. As discussed in the introductory chapters, the Micro:bit V2 has an inbuilt speaker. The programming module comes with inbuilt functions to generate tones and melodies. These can be easily heard using the inbuilt speakers. If we want to hear them louder, we can also connect to any external speaker. In this chapter, we will cover the step-by-step process of dealing with various methods of producing music and speech.

We will explore the following list of topics together...
