Sound Amplifier – Nathaniel

In this Instructable, we'll develop a simplified version of coding a random music piece and test the buzzer with a prototype build with lego pieces to experiment what structure can amplify sound. 

Please note that I'll be testing the music in the MakeCode simulator as well as with microbit. You can test/play your programs in the simulator if you do not have any micro:bit. 

Supplies

1. Lego
2. Micro:bit
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.
