Abstract
We are now going to get our Arduino to make some simple sounds using a piezo sounder. Being able to produce sounds using the Arduino is a great way to add alarms, warning beeps, and alert notifications to the device we are creating. Since version 0018 of the Arduino IDE, a new command has been added that allowed tones to be created easily. We will also find out how to use the piezo as a sensor and learn how to read data from it. Finally, we will look at a light sensor. You will learn how to make simple sounds and pick up the basics of reading analog sensors along the way.
