Themed Sweet Box
This is a sound control device that can be used as a little gift.
produced by: Xinwen Lu
The lock (servo motor)and LED are controled by the sound sensor. Also, the LED is for testing the lock (servo motor) which is inside the box.
It's not easy to adjust the sensitivity of the sound sensor in order to guarantee a high success rate. So for next version, I would like to preset some beats base on some famous songs in order to make diffrent themes boxes.
