Buzzer can playback rtttl format melodies. These can be preset or sent in a json payload through `/play` topic, eg: * Raw text for preset melodies `tetris` * Json for preset or custom melodies, enriched with number of repetition and ms gap: ``` json { "preset": "siren", "loop-count": 3, "loop-gap": 1000 } ``` ``` json { "rtttl": "The Simpsons:d=4,o=5,b=160:c.6,e6,f#6,8a6,g.6,e6,c6,8a,8f#,8f#,8f#,2g,8p,8p,8f#,8f#,8f#,8g,a#.,8c6,8c6,8c6,c6", "loop-count": 2, "loop-gap": 2000 } ``` It can work also without a connection: switch on led on motion detected (*pir*) during night (*photoresistor*). The led light timeout and lux treshold can be set by `HomieSetting`: *lightOnMotionTimeout, lightOnMotionMaxLux* ### Getting Started Compile and upload with [PlatformIO](https://platformio.org/): `pio run --target upload` ### Notes It should be taken as example to explain the [YAHNC](https://github.com/elbowz/yahnc) (Yet Another Homie Node Collection) libs. So mainly to compare a classic HomieNode implementation (eg Buzzer) with the other Nodes (eg `BME280Node`) ### Credits [https://oshwlab\.com/Miraculix200/esp12\-minimal\-with\-headers\_copy\_copy](https://oshwlab.com/Miraculix200/esp12-minimal-with-headers_copy_copy)
