can someone see the problem?
Aside from the complete lack of code? No.
Your code?
Aside from the complete lack of code? No.
He's using app inventor to write an android app - the screen he posted is what the code looks like in app inventor. But you are right that he should post his arduino code too because it's as important here as android application
Maad you're using a block that compares text strings - have you read what it does ? If you move the cursor above the block it says 'reports whether text 1 is lexicographicly greater than text 2' - that's NOT what you want to do here
Use math blocks instead
That was the error I could find but there might be more - make sure you post your arduino code because some of it might be wrong too.
Ohh and why are you sending two values - raw value and voltage ??
Don't tell me you're sending 0 to 1023 value and your arduino code converts that to voltage and send both values ?? it would be a lot more straightforward and easier to send just ONE value. Always try to make stuff as easy as it has to be
is there any reason why you're sending rawvalue?? I can't think of even one so you send calculated voltage and that's it
plus what I said before
