Summary
In Chapter 6, you learned how to make music, alarm sounds, warning beeps, etc, from your Arduino. These sounds have many useful applications. You can, for example, make your own alarm clock. By using a piezo sounder in reverse to detect voltages from it and use that effect to detect a knock or pressure on the disc, you can make a musical instrument. Finally, by using an LDR to detect light, you can turn on a night light when ambient light falls below a certain threshold.
Subjects and Concepts covered in Chapter 4:
- What a piezoelectric transducer is and how it works
- How to create sounds using the
tone()function - How to stop tone generation using the
noTone()function - The
#definecommand and how it makes code easier to debug and understand ...
