Making and reacting to sound is fundamental to daily life. Your next project can use sound quickly and easily to provide indications something is happening or as the perfect accompaniment to your projects use.

Using either Microsoft MakeCode or CircuitPython, you can use sound in your project.

The code will use the Adafruit Circuit Playground Express board. If you have a project that is robotic, you can add the Adafruit Crickit robotics board to Circuit Playground Express which provides the benefit of an amplifier for much better sounds than that provided on the Circuit Playground Express on-board speaker.
