Connecting the Module:
Connect the VCC pin to the power supply (3.3V or 5V).
Connect the GND pin to the ground of your system.
Connect the AO pin to an analog input pin on your microcontroller to get a voltage reading proportional to the sound level.
Connect the DO pin to a digital input pin on your microcontroller to get a HIGH or LOW signal based on the sound threshold set by the potentiometer.
Adjusting Sensitivity:
Use the onboard potentiometer to set the sound level threshold for the digital output. Turn the potentiometer until the desired threshold is reached.
