That is how the heart is turning on, so if u look at the rows of the same color, each is a stage so if u count them excluding the first on because it is alway on u have another 8 stages turning on one after the other and when they reach the (light blue dot) they start turning off on one after the other until they reach the first one (red dot) and then they turn on again, this is done 3 times and then all the leds blink 3 times and then they turn on in they way I just described and so on.
so how can he turn on the other 8 stages with only 4 wires left?
