          本文引用地址：http://www.ex-cimer.com/article/197728.htm
          This simple circuit drives 6 LEDs in 'Knightrider scanner mode'. Power consumption depends mainly on the type of LEDs used if you use a 7555 (555 CMOS version).
          Here's the circuit:
          Note that VDD and GND for the ICs are not shown in the circuit drawing.
