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
- Lego
- Micro:bit & buzzer
- Makecode program (software)
- Battery and wires
- 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.
