Two gates of a 4093 quad, 2-input NAND, Schrnitt-trigger CMOS IC are connected in astable-os-cillator circuits as clocks. The two 4017ICs have six LEDs connected to its first six outputs. As the clock pulses enter pin 14 of the 4017s, the ICs count from one to six over and over as long as the clock pulses are present. When S1 and/or S2 are released, one of the LEDs in each circuit will remain on, indicating a number from one to six.The circuit is set up so that you can roll the dice together by pressing S1 and S2 at the same time, or roll each die one at a time.
