The tone function is capable of generating a single tone, in only one pin at a time. Libraries such as the tone library allow you to generate more tones, but use specific timers of some microcontrollers, which causes incompatibility with many boards. Additional files may be found in the sketchbook under its hardwarecores and libraries directories. Make sure to select a released version of the library. The location of sketchbook folder can be found in the arduino ide at file preferences sketchbook location. The piezo can be connected to digital outputs, and will emit a tone when the output is high. Libraries provide extra functionality for use in sketches, e. To get the frequency of the note to play at each step, we use tonei.
