Below is the schematic diagram of an audio input module. We can produce a DC output voltage that is proportional to the input signal amplitude (the signal strength) using this circuit. One application of this circuit is audio level meter. Other application such as sound-controlled light circuit can be implemented with this circuit as well.

1) DC bias each input signal with a two resistors (voltage divider between GND and 5V) and a capacitor, another voltage divider to a common reference pin ADC. The ADC reference voltage should be set to about 100mv (voltage divider + capacitor).

We use R6 to adjust the frequency of the oscillator circuit internal IC1. In this case, sets the frequency at 18Khz. Input frequency using be in the range 1/10 – 1/15 of the frequencies in above. In the frequency between 1.8kHz to 1.2kHz. The output of the circuit will change state each time to get an input signal comes. The output signal at pin 8 goes to the base of Q1 to …
