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.

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

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.

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.

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