    Your request is too vague for anyone to help you. We need more details: how will the barcode be accessed--with a scanner? What size gate are we talking about? Power source? Other controls (like an unlock control from inside the gate)?

    Also, since you're obviously asking us to help you with your homework (this should really have been posted in the Homework forum), it would help a lot if you showed the slightest bit of initiative and explained what you've figured out and where you're stuck. Don't expect us to just hand you the answer on a silver platter!

    Something about his posts gives me the impression he's building an electronic gate. Possibly with a barcode. :D

    I'll bite, so what exactly do you need help with? Do you have an outline? A plan maybe? Do you have anything at all?

    ..actually i have a plan on this..
    i search for a circuit diagram of a door lock that could possibly open by a barcode device..this device serves as the switch to unlock the door..
    here is the circuit diagram..[​IMG]

    All of this depends on how you want to do it. The electromechanical device on the door is called a "striker" or "door strike". You would connect the bar code reader to a computer however you choose to do so using a port. For example a USB port. You could also connect the reader to a uController and have that do the work. Using a computer you would create a data base with names and numbers for access through the door. You need to write the software for the scanner. When a bar code is scanned the software looks at the data base. If it finds a matching name & number it opens the door with an interface I/O device between the computer and door.

    Well, that's a good start. Perhaps you'd care to post it here so that we can see it?

    to :sir reloadron
    i think the uController you are referring to is the PIC12C508..am i right?

    ..just for the clarification with the your statement above sir, the I/O device you mentioned , is this the striker or door strike and the microcontroller?
