# Keyestudio KS0019 passiv buzzer
![Keyestudio KS0019 passiv buzzer](image.webp)
## Identifikation
| Felt | Værdi |
| --- | --- |
| Produkt-id | KS0019 |
| Type | Passiv piezo-buzzer uden intern oscillator |
| Interface | `IN`, `VCC`, `GND` |
| Forsyning | 3,3–5 V |
Den åbne lydgiver kræver et firkantsignal og kan derfor afspille forskellige
frekvenser. Den skal ikke forveksles med KS0018 aktiv buzzer.
## Tilslutning
`IN` forbindes til en digital udgang og styres eksempelvis med `tone()`.
Kontinuerlig DC giver ikke en kontrolleret tone. Ingen sketches endnu.
