Question:
How loud is the sound around us? In the classroom, outside or when we talk. What ‘music’ would result from overlapping the sounds in these three different environments?

Input: Collect the information using the micro:bit's sound sensor and using the programming shown in the link: Twotones

Programa micro:bit
The buttons have been programmed to allow you to start collecting information (button A), stop collecting data (button B) and delete all the data collected (button A+B simultaneously).
The data is then collected in the Micro:bit's ‘my_data’.

After data collection: Use the TwoTones programme to use the data in .xlsx and transform each piece of data collected.
In my case, I used the following transformations to map sound intensity on instruments:
- Intensity of the sound of the students saying their names in Trumpet (C major; 3 octaves; Auto; Track tempo 3x; Arpeggio None).
- Intensity of the room's ambient sound in Piano (C major; 4 octaves; Auto; Track tempo 1x; Arpeggio None).
- Intensity of the outside sound of footsteps in Double Bass (C major; 4 octaves; Auto; Arpeggio None).

Final product: Música.mp3
