+The idea is that using the analog or digital sound sensor reads sound changes.
+Tracks the highest value and display/store
+Or even print it with a label printer
+
+# Soundsensor
+
+Rotes rechteckiges Board. Blauer Potentiometer. Silberner Zylinder mit schwarzem Aufkleber (rau)
+4 Pins
+Rechte LED (Sensor oben, pins unten) strom
+Linke LED Anzeige wenn Ton registriert wurde.
+
+## Sensitivität einstellen:
+Potentiometer so lange nach links oder rechts drehen bis LED ausgeht.
+Darüber dann einstellen ab wann ein Signal kommen soll.
+
+Laut Beschreibung soll der Potentiometer nur für den DO sein, wenn man diesen
+einstellt ändert sich aber auch der Wert des AO.
