How a Sound Sensor Works
Let’s take a look at your Sound Sensor’s values. Use a USB cable to connect your Studuino to your PC.
Now choose
Test ON
from the
Run
menu. Start Test Mode and you’ll see the Sensor Board displaying
[A3]
Sound Sensor
.
Your Sound Sensor has a range of 0-50, starting at 0 for silence and increasing towards 50 as sounds
become louder. Try clapping near the Sound Sensor or blowing directly on it as you look at the Sensor
Board to see how the values change.
Values change in response
to volume and the
strength of your breath
Once you’re finished, choose
Test OFF
from the
Run
menu to close Test Mode.
