build microcontroller
I'm trying to build a circuit using a PIC microcontroller to convert the analog signal from a microphone.
PIC microcontroller decide to use: PIC16F873A. Compiler: MPLAB
(Is PIC16F873A suitable for this kind of project? Or PIC16F877A?)
Objective:
Light up an LED & activate the DC motor if the sound level is above a certain dB (Need to differentiate at lease 2 different level of dB).
(Only use 1pc. of PIC16F873A/ PIC16F877A without any other IC, is it feasible?)
Draft Flow Chart:
Microphone---> Amplifier---> PIC---> LED/ DC Motor
(This flow correct?)
And please help to find the schematic diagram based on the above project that I intending to do... Thanks in advance!
