Mandalorian Darksaber

This is a remix from the original Darksaber published by Adafruit.
I wanted to build a cheaper version, so I made some changes in the electronics.
I used the following components from aliexpress:
- Arduino nano
- MPU6050
- MP3 dfplayer mini
- Power-up module (from 3.7V to 5V)
- 2x8cm PCB (x2), one for arduino nano and powerup module, the second one for mp3 player and mpu605 sensor
- Li-ion batery 3.7V
- Oval speaker
- 60 Led strip WS2812 5mm
- 4GB mini SD card for mp3 module
- cables & m2 screws

The arduino PIN configuration is the following:
- LED strip: 6
- MP3 player RX: 4
- MP3 player TX: 3
- ON/OFF button LED: 7

I've made changes in 3d design of the blade parts, to print it in two parts
You could follow the original guide in the PDF file.

The zip file contains the wav files to copy in the SD. The files must be copied in order, since the mp3 module plays files using the file positio
