Test Sensor

Hallo liebe Leute,

ich wollte heute mit meinem Arduino Uno den TestSensor mal ausprobieren, leider funzt es aber nicht.
Nach dem einfügen der Library will ich kompilieren und aufspielen, aber es kommt immer folgender Fehler:

Arduino: 1.8.1 (Mac OS X), Board: "Arduino/Genuino Uno"

Fehler beim Kompilieren für das Board Arduino/Genuino Uno.

Kann jemand damit etwas anfangen?

Die Anleitung auf die ich mich beziehe ist folgende:

Danke jetzt schonmal für die Hilfe.

Hab den Fehler gefunden. Es lag an der Arduino Software
