Sound Sense

Setup​

Save the Pearls

We are under the ocean, where there are many Pearls and sharks. A shark is trying to take a pearl, and we should help the pearl to close when the shark is near it.

First, we will add the background and the sprites.

Sound Sense

Then, we will make the shark move in random positions using this code.

Sound Sense

Connect “GND” from the sensor to “GND” at the Arcade, and “VCC” from the sensor to the “3V” at the Arcade. Finally, choose a pin to control it, we connect “SIG” from the sensor to PIN0 at the Arcade

Sound Sense

Now, we will program the sensor, using “analog read” If the sensor reads a low value (greater than 200 depending on your sounds) when shout “CLOSE” to tell the pearl to close!
