    Post all relevant information:schematic, code, thoughts of how the circuit works, and list of your favorite colors and we might be able to help you out.;)





    (Seriously, I'm kidding about that last one!:p)

    according to d ckt i just didint use led display n driver...i just put 8 leds to know the bcd output...hm2007 is used for voice recognition. input to the ic is given through keypad in terms of memory locations and the word to b recognized through mic. it displays the memory location of recognized word. i hv attached datasheet of hm2007.

    You linked to a kit in an earlier post.

    What is the actual schematic and PCB you are using?

    I'm assuming you have access to all the test equipment needed?

    Hello anuja2210!
    i am also thinking of doing a project using HM2007 IC.
    I have a confusion that if i buy any Hm2007 of any market and do not buy the assembled or not assembled kit and connect as per the schematics will it do the work for me?

    This thread is old, you should start a new one.

    What work is left for you then?

    As stated, don't hijack someone else's thread, start your own.
