Get some juice going by closing the switch at the positive supply. Each set of Leds well illuminate in a counter clockwise fashion from the top. When the bottom right set of Leds is lit the circuit is primed. To start the action, open the switch that's underneath the power supply.
** Observing the graph at the top of the screen, I noticed that this particular design truly exemplifies the astable nature of these segmented flasher circuits. Kinda neat..
