# Komponenter

Dette katalog registrerer elektroniske input- og outputkomponenter, der bruges sammen
med boards i Arduino Playground: displays, sensorer, aktuatorer, kommunikations-
moduler og andre komponenter.

Hver fysisk komponenttype får sit eget stabile id og en mappe med:

- identifikation og relevante tekniske data;
- pinout, spændingsniveauer og tilslutning;
- eventuelle adresser, biblioteker og kendte faldgruber;
- links til alle sketches i repoet, som bruger komponenten.

## Navngivning

Nye komponenter placeres i `components/<component-id>/`, hvor `component-id` skrives med små
bogstaver og bindestreger, eksempelvis `bme280-temperature-humidity-pressure`.
Profilen opdateres, hver gang komponenten bruges i en ny sketch.
