【程序】代码程序如下

int a = 12;// LED1接digital_12
int b = 10;// LED2接digital_10
int c = 8;//  LED3接digital_8
int d = 6;//  LED4接digital_6
int e = 4;//  LED5接digital_4
int f = 2;//  LED6接digital_2
int g = 0;//  LED7接digital_0
int h = 1;//  LED8接digital_1
int j = 13;// LED9接digital_13
int k = 19;// LED10接analog_A5 (模拟口A0-A5相当于数据口digital14-digial19)
int m = 18;// LED11接analog_A4
int n = 17;// LED12接analog_A3
int p = 16;// LED13接analog_A2
int q = 15;// LED14接analog_A1
int r = 14;// LED15接analog_A0
//震动开关触发后,延迟时间的调整，采用触发后300+50=350毫秒以保持同步
int delayTime1=300;
//采用矩阵输出字符图形,每个字符高15个点
