Things used in this project

Hardware components

Adafruit Circuit Playground Express

The brains behind the Despacito Box

Rotary potentiometer (generic)

Used for the volume adjustment

Toggle Switch, DPDT

Turns Despacito on or off

Micro-USB to USB Cable (Generic)

Powers the Despacito Box

Alligator Clips

Used to connect all the bits inside the Despacito Box, the height of quality construction

Software apps and online services

Microsoft MakeCode

Used to program the Despacito Box and create the lovely monotone melody it plays

Story

Created as an introductory assignment for a Physical Computing class that required the use of a switch and a knob to control some form of signal. I originally started playing around with how to make the Circuit Playground Express play music through MakeCode, which lead to a friend asking if Despacito was possible, which eventually lead to this... mistake.Its fairly simple, just a potentiometer and a toggle switch connected to the CPX, which was coded to have just the hook from the song that plays on an infinite loop. The potentiometer controls the power fed to the speaker to adjust volume and also lights the LED ring built onto the CPX to display the volume level. Finally the whole thing was wrapped up in a low cost, low profile cardboard housing to keep all those bits and valuable code safe.

Initial layout of parts, first working concept of The Box

The travesty that is the Despacito Box's housing

Secondary use of the volume display, easy access flap for the CPX buttons

First photo taken after the Despacito Box's housing was finished

Dont take this too seriously, by the way :v

This is the entire mess that is the code behind the Despacito Box. One loop controls the volume and lights through the potentiometer, and the other contains all of the notes that had to be put into their own IF statements with an additional IF that turns the sound off in order to be stopped at any point during the series of notes. The section that graphs the potentiometer and controls the lights was modified based on the Adafruit Make it Change guide, the rest was made custom.
