Steffs & Gränds Soundbox

Das Ausstandsgeschenk für zwei Kollegen powered by Arduino.

Soundbox

Die Soundbox ließt über einen RFID-Leser eine RFID-Karte aus und spielt eine ihr fest zu geordnete MP3-Datei ab.

Zusätzlich erhält die Soundbox drei Taster :

• Lauter
• Leiser
• Wiedergabe unterbrechen

Design des Holzgehäuses by Kollege Teflonson.

Benötigte Bauteile

• Arduino Nano
• Mini-MP3-Player Modul
• PCB für das Tonuino-Projekt / Selbst erstellen oder im Set kaufen
• Drei Taster
• Zwei Lautsprecher mit kleiner gleich 3 Ohm
• RFID-Leser

Galerie

Die Bildergalerie zeigt den fertigen Aufbau samt Gehäuse usw.
