Version 1: 7 seg display

555, 4510, 4511

When the push button is pressed, the 4510 counter is controlled by the oscillator composed by the group SN7400N and RC, the count (0 to 6) is displayed by the 7 seg.

The resistor and the capacitor determine the display speed, which must be fast to ensure a random display. The display cycle is reset when the counter reaches 7. At the digit 0 we pass his turn!
