    Default Can you make arduino script for me?

    Gday
    I have an idea but no skills required.

    Arduino board with temp sensor that would send temp plain text string over either TCP socket or RS232.
    I have managed to follow a tutorial on how to do this BUT the TCP data are not in plain text which was done by the eth library used.
    Basically, if you can read plain text output from arduino with Wireshark or putty, I'm interested..

    Cheese.

    Try sending the string in ASCII

    Well thank you, I'm not sure how though..

    This is what I've used last time:

    Code:
    /*
      Web Server
    
     A simple web server that shows the value of the analog input pins.
     using an Arduino Wiznet Ethernet shield.
    
     Circuit:
     * Ethernet shield attached to pins 10, 11, 12, 13
     * Analog inputs attached to pins A0 through A5 (optional)
