SparkFun Sound Detector

Sensors Sound & Audio

Hello,

I bought your sensor but I have one question. The sensitivity of the sensor on the analog output is fine but the digital output is 0. I noticed that if A0> 30, D2 = 1. Can I programmatically change the arduino so that the digital output changes its value for a smaller value?

Can someone help me?

Hello, I sincerely apologize for the delay. Can you please provide any pictures or schematics detailing your setup?

That’s just a picture of a sound detector.

I think TS-Brandon is going to need a bit more than that to help you pretty sure he’s looking for a picture showing how the sound detector is connected up too your arduino or whatever other micro controller you’re using.

I’m using Arduino Uno R3 and SparkFun Sound Detector SEN-14262. It’s the simplest connaection that Sparkfun offers:

VCC-5V,

Gate- D2,

Envelope- A0.

I need to know if I can change the Gate = 1 activation level or if I have to change the R17 resistor.

To increase the gain you’ll have to remove R3 and add R17 according to the sub-section ‘Raising The Gain’ in the “Configuration” section.

Thank you,I will do as you wrote.
