LED sequence, translating code into pattern/ form

a close system of two microcontrollers (PICs). Wires connect the pins of the 2 PICs to each other. The PICs are programmed with a simple logic program consisted of 'IF' statements, and sending 0 or 1 to each other.

This experiment creates a close, linear, binary system: the LEDs turn ON or OFF in a sequence over time. This is one-dimensional situation: LED = point (0 dimensions) turning ON/OFF on the axis of time; a line of LEDs (line = 1 dimension)- the state of each LED is determined by the state of its neighbor LED.
