Closeless Music Box – Marcus Toh

I wanted to create something that can play a sound when people are too close to each other. I chhecked the google what is the meaning of a sound amplifier to know more about it. I tested the sound amplifier onto the microbit. 

I put wheels on the sound amplifier so that it can move

Supplies

1. Lego pieces
2. Microbit, buzzer, battery, battery holder and wires
3. Makecode program (Software)
4. Ruler to measure the prototype.

Step 1:

We research and view a few past prototype examples that use materials like paper cups and cut out milk bottles that can allow sound to amplify.

Step 2:

We experiment using lego pieces that I think reflect a sustainable building which can allow a buzzer to amplify sound. A buzzer about 1.5cm x 1.5 cm which is small enough to be slot inside the prototype. You can build your own design. But must have some hollows for sound particle to vibrate and travel out.

Step 3:

We go to the coding website and take out the following code to download to microbit.
