    and the submission time is so near. with your help i may graduate this simister

    i want to sense wether a baby crying or not?!!!

    so i need audio sensor detector. i looked for all circuits and tried to apply them but i faild. i am a computer engineering students and dont know about electronic issues. i stopped my research in this part and went to interfacing in VB5 using the serial port this is another challenge
    but what iam caring about now is sensing baby sound(cry or not)...

    note: i brought lm3915 and 741 but dont know if they help?!

    You will have much more time when you take the class again next semester.

    It is too bad that you planned your time so poorly.

    Perhaps that in itself will be a learning experience for you.

    Hello,

    You are quite late with your assignment.
    So you will need a microphone, an amplifier, a top detector and the lm3915 to show the signal strength.

    Greetings,
    Bertus
