博客展示了单片机的三个实验代码。包括LED闪烁实验，通过设置引脚输出高低电平实现闪烁；流水灯实验，循环控制多个引脚实现流水效果；交通灯实验，模拟交通灯不同颜色灯的亮灭，每个实验都有对应的代码实现。
void setup() {
// put your setup code here, to run once:
pinMode(10, OUTPUT);
}
void loop() {
// put your main code here, to run repeatedly:
digitalWrite(10, HIGH);
delay(500);
digitalWrite(10, LOW);
delay(500);
LED闪烁实验
void setup() {
// put your setup code here, to run once:
for(int i=2;i<=7;i++)
{
pinMode(i, OUTPUT);
}
}
void loop() {
// put your main code here, to run repeatedly:
for(int i=2;i<=7;i++)
{
digitalWrite(i, HIGH);
delay(100);
digitalWrite(i, LOW);
delay(100);
}
流水灯实验
int pin1=10;
int pin2=7;
int pin3=4;
void setup(){
// put your setup code here, to run once:
pinMode(pin1，OUTPUT);
pinMode(pin2，OUTPUT);
pinMode(pin3，OUTPUT);
}
void loop(){
//put yourmain code here, to run repeatedly:
digitalwrite(pin1，HIGH);
delay(5000);
digitalwrite(pin1，LOW);
digitalwrite(pin2，HIGH);
delay(3000);
digitalwrite(pin2，LOW);
digitalwrite(pin3，HIGH);
delay(5000);
digitalwrite(pin3，LOW);
交通灯实验
