TWSendRawSound
Beschreibung: Dieses Programm liesst die Daten von dem Soundsensor analog ein und sendet Signale per WiFi.
Folgende Verbindungen sind noetig:
Arduino Nano: A3 auf PIN 2 OUT
+5v auf PIN 3 +5 Volt
GND auf PIN 1 GND
Serielle Konsole auf 9600 Baud stellen.
Compile mit Arduino 1.6.2 IDE. Einstellung: Board Arduino Nano
