processor

During the last days I’ve been quite excited about a certain idea I want to report about here, and which I think is quite an entertaining project. During one of my web journeys I recently happened to stumble upon this link over at instructables.com and was fascinated: I was looking at a 5×5 LED matrix that initially blinked its LEDs randomly, but somehow “magically” (with the support of 25 light-dependent resistors) synchronized them very slowly, to finally reach a state of absolute synchronicity – and all this with 25 totally independent control circuits, all based on 25 single atTiny13 microprocessors!! The whole thing should be considered as being a model of large swarms of thousands of male fireflies in sout-eastern asia, which are capable of synchronizing their blinking to attract more female fireflies over a greater distance. For more detailed explanations about the background (and how to set up a physical logic model using AtTiny13 chips and C coding) I want to forward you to the instructables link above as well as to this scientific paper explaining the underlying mathematical theory behind this..
