Sound Control Rotation Box

Back in time, memory of the musical box under Christmas tree was still fresh and sweet. The little princess will start to dance when she hears you. Let’s DIY a music box and let the little princess dance to your song.   First to have the Grove – DC Jack as the controller, it will be the powerful brain of your project. And the Grove – Loudness Sensor as the input while Stepper Motor Driver as the output. Power on and speak to the loudness sensor, once the sensor detects sound signals, the controller will start the stepper motor. See the principle as below and visit our Recipe for the step-by-step tutorial.     Part List: 1 x Grove - Loudness Sensor 1 x Grove Mini Fan 1 x Gear Stepper Motor with Driver 1 x Grove – Logic DC Jack 1 x 9V to Barrel Jack Adapter 1 x 9V Battery 1 x Laser-cutting Moon-shape Box  1 x Clay  1 x Bamboo Stick   You can also develop other projects with the modules.
