    HI,

    Is there a good site / book / projects that explain what happens when
    we send some information from the keyboard to a device that is
    connected via a serial/usb port of the PC.

    Say, for example, I hit the digit 6 for any device that is connected to
    my PC via the serial port or USB port or any other port and the device
    displays the digit 6 on the LCD or any other device that sets its time
    counter to 6 seconds, or makes sound for 6 seconds, etc....

    I know there is a micro controller or some kind of PCBs on the
    electronic devices that understands any data that I send from the
    computer, but I would like to know what exactly is happening and how
    the devices understand the data that I send from the computer and
    convert it into the appropriate commands to perform?

    What software can I use to design the user interfaces to capture the
    data in the computer and how does the device understand the same ?

    Kindly let me know of any videos / books / online sites that explain in
    detail of these simple and basic concepts.

    Thanks in advance,
    Sarita
