Der Sketch ist noch im Entstehen aber hier wie er bisher aussieht (den Taster habe ich beim Foto zuerst weggelassen, der Einfachheit halber). Eine zweite Spannungsquelle ist leider nicht so einfach möglich, da das Ganze ein Midi Controller werden soll und nur via USB gespeist sein soll - oder ist das anders gemeint?
