使用for循环作为延迟的替代方案?

仅仅询问for循环函数是否用作计时器而不是延迟,也会在主循环中对其他代码行造成不必要的干扰。

void okLED() {
  for (long i = 0; i < 150000; i++) {
    digitalWrite(LED_BUILTIN, HIGH);
  }
  for (long j = 0; j < 150000; j++) {
    digitalWrite(LED_BUILTIN, LOW);
  }
}

void slowLED() {
  for (long i = 0; i < 25000; i++) {
    digitalWrite(LED_BUILTIN, HIGH);
  }
  for (long j = 0; j < 20000; j++) {
    digitalWrite(LED_BUILTIN, LOW);
  }
  for (long k = 0; k < 25000; k++) {
    digitalWrite(LED_BUILTIN, HIGH);
  }
  for (long l = 0; l < 110000; l++) {
    digitalWrite(LED_BUILTIN, LOW);
  }
}

像这样的东西。

我想建立一个基于Arduino的尾灯系统,该系统与来自RC控制的油门信号互连。
