Hallo,
ich habe auf youtube ( RFID Süßigkeitenbox (+ Twitter) folgenden Code gefunden.

Mir fehlt aber leider die API und Datenbank in der Anleitung um es nachzumachen steht:
"Der Webserver ist ein Nginx mit PHP-extension auf einem Raspberry Pi. Als Datenbank läuft eine MariaDB. Da ich das Rad nicht (mehr) andauernd neu erfinden möchte, dient Laravel 5.3 als Framework.
Das Theme kommt auch nicht von mir, sondern ist ein freies Admin-Theme namens "Matrix". Dieses habe ich mir mittels Bootstrap und etwas Javascript (JQuery) zurecht gebogen. Nach erfolgreicher Arbeit sieht das Ganze dann so aus:"
Gibt es da welche die mir helfen können?
Liebe Grüße
