:description: Instructions for setting up a buzzer to play tones and rtttl songs with ESPHome.

**NEW:** Or play the song using the I2S speaker.

The ``rtttl``, component allows you to easily connect a passive piezo buzzer to your microcontroller
|
|
and play monophonic songs. It accepts the Ring Tone Text Transfer Language, rtttl format (`Wikipedia
|
|
<https://en.wikipedia.org/wiki/Ring_Tone_Transfer_Language>`__) which allows to store simple melodies.

Buzzer Module
|
|
|
|
Overview Using a passive buzzer
|
|
-------------------------------
|
|
|
|
It's important that your buzzer is a **passive** one, if it beeps when you feed it with 3.3V then it is not
|
|
a passive one and this library will not work properly.
|
|
|
|
The tone generator needs a PWM capable output to work with, currently only the
|
|
:doc:`ESP8266 Software PWM Output<output/esp8266_pwm>` and
|
|
:doc:`ESP32 LEDC Output <output/ledc>` are supported.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
output:
|
|
- platform: ...
|
|
id: rtttl_out
|
|
...
|
|
|
|
rtttl:
|
|
output: rtttl_out
|
|
id: my_rtttl
|
|
gain: 60%
|
|
|
|
Overview Using the I2S speaker
|
|
------------------------------
|
|
|
|
The tone generator can instead be used with a :doc:`Speaker </components/speaker/index>` to output the audio.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
speaker:
|
|
- platform: ...
|
|
id: my_speaker
|
|
...
|
|
|
|
rtttl:
|
|
speaker: my_speaker
|
|
id: my_rtttl
|
|
gain: 0.8
|
|
|
|
Configuration variables:
|
|
------------------------
|
|
|
|
- **output** (**Exclusive**, :ref:`config-id`): The id of the :ref:`float output <output>` to use for
|
|
this buzzer.
|
|
- **speaker** (**Exclusive**, :ref:`config-id`): The id of the :ref:`speaker <i2s_audio>` to play the song on.
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
|
|
- **gain** (*Optional*, Percentage): With this value you can set the volume of the sound.
|
|
- **on_finished_playback** (*Optional*, :ref:`Automation <automation>`): An action to be
|
|
performed when playback is finished.
|
|
|
|
Note: You can only use the **output** or **speaker** variable, not both at the same time.
|
|
|
|
``rtttl.play`` Action
|
|
---------------------
|
|
|
|
Plays an rtttl tone.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_...:
|
|
then:
|
|
- rtttl.play: 'siren:d=8,o=5,b=100:d,e,d,e,d,e,d,e'
|
|
|
|
Configuration options:
|
|
|
|
- **rtttl** (**Required**, string, :ref:`templatable <config-templatable>`): The rtttl string.
|
|
|
|
You can find many rtttl strings online on the web, they must start with a name, then a colon: ``:`` symbol
|
|
and more codes of the song itself. Tip: you can try playing with the values of d=16,o=6,b=95 and make the
|
|
song play at a different pace or pitch, e.g. setting o=7 instead will cause the song to play on a higher pitch.
|
|
|
|
|
|
``rtttl.stop`` Action
|
|
---------------------
|
|
|
|
Stops playback.
|
|
|
|
.. code-block:: yaml
|
|
|
|
on_...:
|
|
then:
|
|
- rtttl.stop
|
|
|
|
All actions
|
|
-----------
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID of the rtttl if you have multiple components.
|
|
|
|
``rtttl.is_playing`` Condition
|
|
------------------------------
|
|
|
|
This Condition returns true while playback is active.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# In some trigger:
|
|
on_...:
|
|
if:
|
|
condition:
|
|
rtttl.is_playing
|
|
then:
|
|
logger.log: 'Playback is active!'
|
|
|
|
|
|
Common beeps
|
|
------------
|
|
|
|
You can do your own beep patterns too! Here's a short collection so you can just use right away or tweak them to your like:
|
|
|
|
.. code-block::
|
|
|
|
two_short:d=4,o=5,b=100:16e6,16e6
|
|
long:d=1,o=5,b=100:e6
|
|
siren:d=8,o=5,b=100:d,e,d,e,d,e,d,e
|
|
scale_up:d=32,o=5,b=100:c,c#,d#,e,f#,g#,a#,b
|
|
star_wars:d=16,o=5,b=100:4e,4e,4e,8c,p,g,4e,8c,p,g,4e,4p,4b,4b,4b,8c6,p,g,4d#,8c,p,g,4e,8p

|
Test setup
|
|
----------
|
|
|
|
With the following code you can quickly setup a node and use Home Assistant's service in the developer tools.
|
|
E.g. for calling ``rtttl.play`` select the service ``esphome.test_esp8266_rtttl_play`` and in service data enter
|
|
|
|
.. code-block:: yaml
|
|
|
|
song_str: 'scale_up:d=32,o=5,b=100:c,c#,d#,e,f#,g#,a#,b'
|
|
|
|
