Hallo Ihr Lieben,

Da ihr mir schon einmal so Toll geholfen habt, wende ich mich gleich wieder an euch!

Es gibt ein Problem mit folgendem Sketch:

In Zeile 145 kommt folgende Meldung:
exit status 1
‘proceed’ was not declared in this scope

ich hoffe ihr könnt mir mal wieder helfen

Hi Stephan,

das ist ein Easy-fix. Scheinbar hast du in dieser Zeile (145) nur den Doppel-Slash // gelöscht. Wenn man ihn dort einfügt, läuft der Code wieder.

Liebe Grüße

Stefan

Hallo guten Abend an alle,
ich hätte ein Wunsch ist jemand der mir helfe möchte?
ich habe das Projekt Led Brücke übernommen und nach gebaub
aber ich glaube der Encoder trotzdem viel gegoogelt ich kann
das nicht richtig anschließen (ich habe der Pin minus an minus angeschlossen, DT am 5 von Arduino und CLK am 6
am Arduino, der Taster an minus und am Pin4 von Arduino und die Led Strip am Pin 2, ja es blinkt zwar dann macht Pause, wenn ich der Taster Drücke passiert nichts und wenn ich der Encoder drehen dann erscheint
kurz eine Farbe und dann wird wieder weiß,
ich würde mich sehr freuen wenn jemand mir helfen kann.
Ich bedanke mich in voraus und verbleibe.
Mit freundlichen Grüßen
Antonio
