Sound Amplifier-Vannson

In this step by step sharing how I approach building sound amplifier and make the project sound louder.

The efforts was after watching a few videos to understand what sound amplifier is. I use lego to build the prototype and modified it to test whether solid is a good medium for sound to travel. In the process, I realised I need to make a lot of space for the microbit to fit in.

Supplies

In making, tools are very important. The tools I used are

1. Lego
2. Micro:bit & 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.
