Electronic Brick - Sound Sensor/Microphone Brick

Customer Reviews

I have a question. Review by Junewon

I bought this item.
I tested this sound sensor with arduino nano.
But I think this item's sensitivity is not good.

I just connect to 5V, GND, AnalogRead of arduino(A0.. etc). just 3 line.
But there is small movement of sensor output. as like 429~432..
When I take big loud, then changed to 440...

I expected sensor's output is 0 to 1023, if input voltage is 5V.
Is this wrong??

What is problem?
(I tested 2 sensor, and get same result..) (Posted on 9/16/2014)
