This Instructable will show how to make a colourful dice using the technique of charlieplexing with RGB LEDs. The project uses 7 RGB LEDs arranged in the form of dice. Each RGB LED has three separate LEDs inside so that makes a total of 21 LEDs and they have been controlled by 4 I/O pins of ATTiny13V Microcontroller. But according to the theory of CharliePlexing,we can only control 12 {n(n-1)} LEDs from 4 I/O Pins.
