The doorbell, remote doorbell and Teletype show how to generate an audio tone in Turtle Art, the following code in the Pippy Activity can generate a tone of variable duration (from Guzman Trinidad).
The doorbell, remote doorbell and Teletype show how to use the Python block to generate an audio tone in Turtle Art.

The volume level can be amplified with a CD or tape player or amplified PC speakers. This can be used for resonance experiments including Chladni plates.

===Gliding tone===
Here is the program to generate a sawtooth gliding tone, be sure to load the Python block with the inbuilt Python code sample <i> sinewave.py </i>

===Mouse slider tone===
Here is the code to use the mouse to adjust a slider which sets the tone. Be sure to load the first Python block with the inbuilt Python sample <i>push_mouse_event.py</i> and the second with the inbuilt Python code sample <i> sinewave.py </i>

===Using Pippy to generate a tone===
The doorbell, remote doorbell and Teletype show how to generate an audio tone in Turtle Art, the following code in the Pippy Activity can generate a tone of variable duration (from Guzman Trinidad).
import pippy
f= input ("Ingrese la frecuencia a generar (Hz):")
t= input ("Ingrese el intervalo de tiempo (s):")
pippy.sound.playSine(f, 5000, t, 0)
pippy.sound.audioOut()
