Internal timer with the interruption of the experiment by the 8051 internal timer 0 by way of a work, that is used as a 16-bit timer, every 0.1 seconds a T0 overflow interrupt. Requested by the simulation cycle lantern. Lantern patterns change as follows: from the middle (L4, L5) followed by the two began to accumulate on both sides of light by the middle of the whole-liang (L4, L5) followed by both sides of the two began to accumulate extinguished body by both sides ( L1, L8) followed by two to the middle of cumulative lit all-liang by both sides (L1, L8) followed by two to the middle of cumulative extinguished. The timing interval is 0.5 seconds, and so the cycle.
