This device can show you the fastest way by LED (WS2812) to solve the 3x3 Rubik's Cube. We use OpenCV to get the color data from a web camera, and use Two-Phase algorithm to solve it. The solution will transfer to LED light road so users can follow the light , and then solve the rubik's cube. https://www.notion.so/stu00608/Rubik-s-Lead-d9af09042f5543d1b88b3603d3bff181
