java fehlermeldung beim öffnen von einer *.ino datei

hallo allerseits,

bin zwar schon eine weile im forum dabei, aber mit arduino ist es mein erster kontakt...

habe beim öffnen einer datei in der arduino IDE (unter ubuntu-linux) diese fehlermeldung bekommen und kann damit absolut nichts anfangen, könnte mir bitte jemand helfen und einen tipp geben was zu tun ist?

Code:

Wenn der Dateiname nicht mit einem Buchstaben beginnt, kann dieser Fehler auftreten.

hi Sisor,

ok, am anfang war ein buchstabe aber mittendrinn eine leerstelle, was evtl. auch die ursache gewesen sein könnte, oder? Jetzt heisst das file "obstacle_avoidance.ino". Ist von sainsmart, evtl. zu kompliziert um damit anzufangen? Ich habe teile bei sainsmart bestellt, da möchte ich die testen, wenn sie da sind :-)

lässt sich in der arduino IDE öffnen, beim compilierversuch kommt:

jetzt weiss ich dass es bedeutet, dass bestimmte libs fehlen. Muss ich diese (welche? alle?) in das verzeichnis mit der zu compilierenden datei kopieren, oder gibt es eine möglichkeit das über pfade in der IDE zu machen? Die IDE bietet die möglichkeit die libs zu includen, reicht das schon?

danke erstmal...

Unter Windows kommen Bibliotheken standardmäßig nach: ...\Eigene Dokumente\Arduino\libraries
Allgemein: [Sketchbook-Speicherort]\libraries
Sketchbook-Speicherort kann man in 'Datei'->'Einstellungen' erfahren.
