I've been trying install Processing's library (processing 2-arduino.zip)
I've gone to sketch>Include Library> Add .ZIP Library...
Then I 've selected the zip file and the following message appeared:
I am having the same problem. My error is "Invalid library found in /Users/Kelly/Documents/Arduino/libraries/arduino: Missing 'author' from library". I can't even upload a simple program to my board. pert, I cannot edit the library.properties. Lucas and princeJB, were you able to fix this problem?
