使用遙控器測試

void setup() {

}

void loop() {
tone(8,38000);
delay(1000);//不能太長
noTone(8);
delay(1000);
}
//使用示波器觀看

//發射端 TX HIGH 不發射紅外線
//TX LOW 發射38KHz 紅外線
#define pin_38k    7
int key1 = 12;
int val;

void setup()
{
pinMode(key1,INPUT_PULLUP);

Serial.begin(1200);
tone(pin_38k, 38000);
}

void loop() {
    val = digitalRead(key1);
    while (val == LOW)
{
    Serial.print("1");
    delay(250);
    val = digitalRead(key1);
}
}

//接收端

int LED1 = 9;
String s;
void setup()
{
Serial.setTimeout(50);
Serial.begin(1200);
pinMode(LED1,OUTPUT);

}

void loop()
{
if(Serial.available())
{
    s = Serial.readString();
    if (s == "1")
    {
      digitalWrite(LED1,HIGH);
      delay(1000);
      digitalWrite(LED1,LOW);
    }
}
}

readString() 方法的行為是不論有無資料可讀取、也不論資料長度，都會等到 serial.setTimeout() 指定的工作時間(ms)截止後才返回。(若傳送字串長 timeout 時間需增加)
這段期間內讀取的資料全部放入字串 (String) 回傳。
String s=Serial.readString();
如果沒有資料，則字串長度為 0
s.length 為 0
