Thingspeak probleme

hallo zusammen,


nach dem einfügen des thingspeak teiles in mein projekt blink jetzt die led pin 13  aber wieso und daten bekomme ich auch nicht in das thingspeak geschrieben, hat wer eine lösung oder idee?
die daten aus dem solarregler bekomme ich ausgelesen und via rs auch angezeigt.
verwendet wird ein arduino mega 2560 und eth shield
