ws2812 light cube, light cube (open source)

A cube made using w2812b.

It contains a gravity sensor and has different lighting effects on different sides. (The charging port cycles down all effects)

It is for personal study and communication only, please do not use it for any form of commercial use.

The main control part is designed according to the Arduino nano. The chip I bought (atmega328p) does not have the Arduino nano's Bootloader (boot program), so I need to burn the Bootloader to the chip myself and configure the fuse bits. Thanks to the serial port chip, after configuring and connecting the data cable, you can use Arduino to program the Rubik's Cube!

The picture model is only modified based on the original version: the charging port and switch, and then a few empty pads (used to add the battery indicator light) are added. And replace the original CJA1117B-3.3 (original version) with HT7333-3 (pictured version). When using, be careful not to install it wrong (their pins are different), or replace it with other buck chips by yourself.

Replenish:

Since the attitude (gravity) sensor used is small, caution is required! Make sure you are capable of soldering this component!
