And your question ? please post your sketch within </> code-tags and use ctrl-T auto-format for easier viewing.
I'm trying to do the "same" thing, but in my case, there's a servo motor that the fingerprint sensor controls to... The problem is that the POST request doesn't works with fingerprint sensor, I don't know why... Maybe is the serial port communication conflict, but I don't know, I want to solve this problem too.
