Thanks for your answer. But I still cant get this working.
Downloading and unpacking arduino-1.0.2-windows.zip results in a different files and library structure than you described. However, since the basic examples work fine, I think the basic setup is OK.
I assume I should be able to choose an example from File/Examples (I have a German version, but that's probably the translation).
- I try File/Examples/LiquidCrystal/HelloWorld.
- I successfully compile it with CTRL-R.
- I successfully upload it with CTRL-U
But the display remains showing the very same like the original photo I linked in my first posting. After a minute or so the backlight went off. I have the impression that there's something wrong with this hardware but I'm trying to make sure it's not ME doing something wrong.
What makes me quite sure that the hardware is broken is that after the backlight went off, it went on again after I touched the board. So I think there probably a bad solder joint somewhere. Or whatever. But before complaining to the seller I would like to be sure it's not me doing something wrong.
