That is not the question you asked in your first post.not at all. i have various diagrams but my present problem is how to know the decibel output of my circuit
You forgot to say what the PIC microcontroller will do in this circuit. The circuit works fine without a microcontroller.Please I would like to know how to incorporate a PIC micro controller into the noise detector circuit, How would I do that.
The circuit detects any sounds. Noise or voices are some of the sounds that trigger the LED. Simply add more circuits to trigger at different dB levels.I would also like to know how to integrate a voice alarm with the circuit to indicate the dB level of the noise.
Why do you simply COPY a circuit (the circuit shown from RED Circuits)? Aren't you supposed to design your own circuit for a final year project?hi...is this project a success?'cause i intend to do one for my final year project and perhaps i might need some help if i found problems on this
