Hello,

Your Processing code is looking for this:

  if (finalRead.equals("7320574163")) {
    state = 1;
  }

You are sending this:

That is why it is not working.

I previously made this suggestion:

You have to decide what to do:

  • Modify your Processing code to look for the String you are sending with the Arduino code you are using as is:
    "data: 49 CD 4A A3"
  • Modify your Arduino code to send a String to match your Processing code.

The data seems to be correct:

The example I provided here sends the correctly formatted String data and Processing is receiving it and it working as expected.

I kept it simple as this is your project.

Give this some more thought.
Try to get it working as is.
Clean it up later.

:)
