# Useless Music Box with Arduino Nano
The useless box, with a twist: when you flip the toggle switch the lid lifts, a printed finger comes out, a buzzer plays one of ten short tunes (Super Mario, Tetris, Star Wars and friends), and the finger flips the switch back off before the lid closes. Two MG90S micro servos (SG90 also fits), an Arduino Nano on an expansion board, a passive buzzer and an 18650 cell in a holder with a 5 V output; everything else is printed.
What you get in the download:
- the six print files: box, hinged lid, fixed lid, switch finger, lid finger and cable holder,
- a Build Guide PDF: firmware first, then printing, wiring, finger alignment and assembly,
- a Bill of Material PDF with every purchased part and a shop link per row.
The firmware is a small PlatformIO/Arduino project by the original author; the build guide tells you which version to flash and how to adjust the servo end positions for your print.
This is a remix of the Useless Music Box by Dawieder on Printables, updated and refurbished for modern use with a current-parts Bill of Material and a rewritten build guide.
