以下是我最早拿範例做修改並拿掉else..幾次試下來加上拉電組比較穩(摸電線亂亮LED)
問題還是在loop內控制2個LED.我只想做各1次亮滅後停止(紅外線ON時不要無限閃爍).
然後..
斷開紅外線pinMode(2, INPUT)後.再紅外線ON時.2顆LED亮滅各1次..

上面程式只要紅外線是on就會無限閃爍
要在程式裡加計數器限制就好了
void setup() {
pinMode(2, INPUT);
pinMode(3, OUTPUT);
pinMode(4, OUTPUT);
digitalWrite(3, LOW);
digitalWrite(4, LOW);
int sun=0;
}
void loop() {
if (digitalRead( 2 == HIGH && sun == 0) ){
digitalWrite(3, HIGH);
delay(1000);
digitalWrite(3, LOW);
delay(1000);
digitalWrite(4, HIGH);
delay(1000);
digitalWrite(3, LOW);
digitalWrite(4, LOW);
sun += 1;
}
else if (digitalRead(2 == LOW && sun == 1)) {
sun = 0;
}
}
這樣就會在紅外線在ON的時候只執行一次 |
