工业控制技术实验程序

1、试验一程序#define PWM 6unsigned char led6=*, *,*,*,*,*;void setup() for(int i=0;i6;i+) pinMode(ledi,OUTPUT); pinMode(PWM,OUTPUT);void loop() for(int i=0;i-1;i-) /反循环点亮 digitalWrite(ledi,HIGH); delay(100); digitalWrite(ledi,LOW); for(int j=0;j3;j+) /全部灯闪烁三次 for(int i=0;i6;i+) digitalWrite(ledi,LOW); delay

2、(500); for(int i=0;i6;i+) digitalWrite(ledi,HIGH); delay(500); for(int k=0;k-1;k-) /全部灯慢慢点亮 analogWrite(PWM,k); delay(20); for(int i=0;i6;i+) / 全部灯熄灭 digitalWrite(ledi,LOW); while(1);样例2：#define PinA 2 /中断0unsigned char led8=38,39,40,41,42,43,44,45;volatile unsigned char j;void setup() for(int i=0;i
