As you can probably see it is not possible to read those images.

And it looks as if your problem is with your App Inventor code so I suspect you need to ask on an App Inventor Forum.

If the problem is with your Arduino program then please post the program code here. And please post your code between [code] [/code] tags so your code looks like thisand is easy to copy to a text editor.
