Stap 6: Instellen van de vingerafdruk-Scanner
Voor de communicatie met de FPS, ik zal het gebruiken van deze bibliotheek Arduino door Josh Hawley (directe download voor de bibliotheek hier).
Om te controleren of de communicatie met uw vingerafdruk-scanner werkt, zou ik dit voorbeeld knipperen uploaden.
De vingerafdruk-scanner heeft zijn eigen geheugen voor het opslaan van de vingerafdrukgegevens. Dus, nadat u hebt gecontroleerd dat de FOD werkt, uploaden van de schets van dit voorbeeld als u wilt uw vingerafdruk toevoegen aan de database onder id #0. De seriële console te openen en volg de instructies.
Code:
Knipperen in het volgende voorbeeld:
