Love it - this is the best reason to allow "smart" devices in the classroom.

I wonder - could it pick up the sound of a bouncing ball?

I'm still learning my way around Instructables. See the bouncing ball profile.

Here is your answer Kiteman! Bouncing ball decay profile with OsciPrime.

That was "great idea Kiteman".

Great I sensitivities kite man. You can set the trigger to any sensitivity. The closer to the baseline the more sensitive. I am sure it would pick up a bouncing ball. I knew it wouldn't take long for folks to come up new uses.
