[erledigt] Zahl an Serielle senden, wenn es angef. wird.

Manuel001

Hallo!

Ich möchte folgendes realisierten:
Wenn über die Serielle der Text "Überschuss?" rein kommt, möchte ich über die Serielle die Zahl 0-9 zurück senden, je nach aktuellem Überschuss. Dass ich aus dem Überschuss die Zahl 0-9 erzeuge funktioniert schon. Aber wie ich diese Zahl dann an die Serielle zurück gebe, habe ich keinen Plan. Ich habe an diese Stelle mal ein Change Node eingefügt, weiß aber nicht so recht, was ich damit anfangen kann. Kann mir bitte jemand auf die Sprünge helfen?
