说明：  通过定时器1控制八个LED实现不同样式的循环点亮，首先13，然后24，35，46，57，68之后是四个灯1357，2468，之后全部点亮再全部熄灭。(Through timer 1 control eight LEDs to achieve different styles of cycle lighting, first 13, then 24, 35, 46, 57, 68 followed by four lights 1357, 2468, and then all lit and then all off.)

线路通断检测器的设计： 1．用压电陶瓷蜂鸣片作为电声元件。 2．用两根导线作为测试探针 3．线路通断是通过测试电阻的大小来判断，有以下三种情况： （1）若150Ω<Rx<900Ω，则蜂鸣片不发出声响。 （2）若Rx>900Ω或者Rx<150Ω，则蜂鸣片发出间歇式的滴－滴声响。 以上各临界阻值（150Ω和900Ω），允许误差±10％ 4．＋15V直流稳压电源需要设计。 (Line-off detector design: 1. Piezoelectric ceramic buzzer as the electro-acoustic components. 2. As a test probe with two wires 3. Lines off by testing the resistance to determine the size, the following three conditions: (1) If 150Ω <Rx <900Ω, the buzzer is not audible. (2) If Rx> 900Ω or Rx <150Ω, then the buzzer sent intermittent drip- drip sound. Above the critical resistance (150Ω and 900Ω), tolerance ± 10 4.+15 V DC power supply need to design. )
