This DIY project might be the simplest design of tri-color LED cubes out there. Without using complicated components such as shift registers, decade counters, reference shifting transistors or any other components to control LEDs, this project focuses on a much simpler, cost effective design. Other LED cubes with extra components can cost upwards of $150, leaving you with an empty wallet and a schematic-induced headache. This LED cube utilizes Charlieplexing and can operate using only 16 digital pins of an Arduino controller with no additional hardware besides the RGB LEDs themselves.
