1、试验一程序#definePWM6unsignedcharled[6]={*,*,*,*,*,*};voidsetup(){for(inti=0;i<6;i++)pinMode(led[i],OUTPUT);pinMode(PWM,OUTPUT);}voidloop(){for(inti=0;i<6;i++)//正循环点亮{digitalWrite(led[i],HIGH);delay(100);digitalWrite(led[i],LOW);}for(inti=5;i>-1;i--)//反循环点

2、亮{digitalWrite(led[i],HIGH);delay(100);digitalWrite(led[i],LOW);}for(intj=0;j<3;j++)//全部灯闪烁三次{for(inti=0;i<6;i++){digitalWrite(led[i],LOW);}delay(500);for(inti=0;i<6;i++){digitalWrite(led[i],HIGH);}delay(500);}for(intk=0;k<256;k++)//全部灯逐渐熄灭{analogWrit

3、e(PWM,k);delay(20);}for(intk=255;k>-1;k--)//全部灯慢慢点亮{10analogWrite(PWM,k);delay(20);}for(inti=0;i<6;i++)//全部灯熄灭{digitalWrite(led[i],LOW);}while(1);}样例2：#definePinA2//中断0unsignedcharled[8]={38,39,40,41,42,43,44,45};volatileunsignedcharj;voidsetup(){for(

4、inti=0;i<8;i++)pinMode(led[i],OUTPUT);pinMode(PinA,INPUT);//D2脚为输入attachInterrupt(0,count,RISING);}voidloop(){while(1){digitalWrite(led[j],HIGH);if(j>=8){j=0;for(inti=0;i<8;i++)digitalWrite(led[i],LOW);}}}voidcount(){j++;}10试验二程序constintencoderPinA=3;
