Sound Amplifier = Mingjie

In this project, I am trying to build a sound amplifier to make music louder and more exciting.

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.
