Version 2: Three dice with LED display
555, 4510, 4028
Here we have three dice, a dice with three faces, one with six faces and another with 4 faces. Everything is controlled by a timer 555 at a frequency of 5kHz. The top and middle dice have their own counter with a different display speed. The display cycle is reset when the counter reaches 6. At the digit 0, we pass his turn!
