    Helo all, im new to this forum.

    pLEASE I NEED HELP ME , i am new to microcontroller and even c programing.

    I want to make a project Electronic code lock with LCD and Alarm.

    i am planing to use 89C51 microcontroller,I would like to know were i would start from what is the first thing am suppose to do .plEASE Let me know in time the submission time is close.

    Thanks please please just leave a comment .hep me i dont want to fail.please

    Welcome to the forums.

    From your post, I will assume this is for an assignment.

    Searching for code lock projects will surely bring up some items. Here is one out of the projects archive - http://forum.allaboutcircuits.com/showthread.php?t=15030

    You seem to have put this off a bit long. Learning to program plus some electronics will keep you busy for some time.

    i have not done much, what i have done is just to make research on microcontrollers, i am a big novice in this field but i want to get high marks with the help of you guys. this is how i want my project to work:

    ITwould have the following ,

    LCD.
    MICROCONTROLLER.
    ALARM
    4 X 4 KEYPAD. AND I WANT MY PROGRAMING TO BE IN c LANGUAGE

    FIRST
    DO I NEED TO INTERFACE THE COMPONENTS BEFORE PROGRAMING? OR DO I NEED TO LEARN PROGRAMING FIRST BEFORE I START ANYTHING.

    PLEASE GUIDE ME ALONG WITH THE PROJECT. (hope am not begging to much )

    Surely the school did not simply drop this assignment on you with no preparation.

    what resource have you do draw on? Is there a lab to use? Is there test equipment available. Are there components available to you - power supplies, resistors, capacitors, keyboards, logic IC's, and so on?

    Are you constrained to using some specific microcontroller? Do you have available a programmer for it, and the C compiler?

    I might mention in passing that examples of and the programming for code locks are easy to find. Google turns up 991,000 hits, for instance.

    @beenthere. i have access to all the materials you have mentioned.(programmer,compiler and others OK

    this is what i have made my research on so far
    i want to use a PIC microcontroller with MPLAB
    i want to use a 4x4 keypad.
    and i want to use an alarm circuit when there is a wrong password. ok thats all. so where do i start from . programing? or where.?

    again C program and assembley which is easier for a learner... as in for programming microcontrollers

    That may be a matter of personal preference. I like assembler, but many people like C and it's variants.

    With all the example that may be found in the internet, starting your process of learning programming would make sense.
