一个大的猫窝,voidcat

就是不知道一直闪会不会坏掉。针脚只能用有波浪线的

int led = 3;

void setup() {
// put your setup code here, to run once:

}

void loop() {
// put your main code here, to run repeatedly:

for(int i = 10; i<255; i++)
{
analogWrite(led,i);
delay(5);
}

for(int i = 255; i>10; i--)
{
analogWrite(led,i);
delay(5);
}
}
