Sound Amplifier - Loh Teck Yee

I build a lego prototype with a space for the micro:bit to fit in.

My prototype has added wheels to make it more portable. The idea is to increase its portability to far-flung area. It also has plants to make it look more beautiful. I also added a disco ball to make it stylish.

Supplies

1. Lego
2. Micro:Bit and buzzer
3. Makecode program (software)
4. Battery and wires
5. Ruler to measure 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.
