Fehlersuche, Arduino, Menü, Strommesssensoren

International Deutsch
1

Hallo, ich bin noch nicht ganz so lange dabei und versuche gerade zwei Strom und Spannungssensoren in mein Menü einzufügen.

Was ich nicht ganz blicke ist, wie man die Sensorwerte von einander unterscheidet und das so
aufschreibt. Also dass beide unterschiedliche Werte ausspucken...

LG Felix

Danke!

Im englischen Teil des Forum müssen die Beiträge und Diskussionen in englischer Sprache verfasst werden.
Deswegen wurde diese Diskussion in den deutschen Teil des Forums verschoben.

Da liest du wieder von A0. Du meinst vermutlich
Sensorwert2 = analogRead(Sensor2);
, falls du den an A1 angeschlossen hast.

So wie Du angefangen hast:

hättest Du hier

weitermachen müssen.

TIPP: Bevor Du den Code postest, einmal alle überflüssigen Leerzeilen löschen.
Das liest sonst kein Mensch.
Die entscheidene Zeile ist:

Das Ding wird zu:

Sensorwert2 = analogRead(Sensor2);

Ich hoffe das ist Gelichstrom den Du da mißt.
