米思齐Mixly图形化编程---呼吸灯与可调档位灯

实验材料与环境

硬件：Arduino、LED灯、按钮
软件：Mixly IDE

软硬件连接

两个实验的接法相同，我的接法是：
灯：9号（因为灯的亮度需变化，所以选择接：3，5，6，9接口）
按钮：8号

【实验一】呼吸灯

1.图形化编程块

2.代码块

volatile boolean status;

void FadeOff(int time) {
  for (int i = 255; i >= 0; i = i + (-5)) {
    if (digitalRead(8) == LOW) {
      delay(200);
      if (digitalRead(8) == LOW) {
        status = !status;
        while (digitalRead(8) == LOW) {
        }

      }
      if (status == 0) {
        return;
      }

    }
    analogWrite(9,i);
    delay((time / (255 / 5)));
  }
}

void FadeOn(int time) {
  for (int i = 0; i <= 255; i = i + (5)) {
    if (digitalRead(8) == LOW) {
      delay(200);
      if (digitalRead(8) == LOW) {
        status = !status;
        while (digitalRead(8) == LOW) {
        }

      }
      if (status == 0) {
        return;
      }

    }
    analogWrite(9,i);
    delay((time / (255 / 5)));
  }
}

void setup(){
  status = 0;
  pinMode(8, INPUT_PULLUP);
  pinMode(9, OUTPUT);
  Serial.begin(9600);
}

void loop(){
  if (digitalRead(8) == LOW) {
    delay(200);
    if (digitalRead(8) == LOW) {
      status = !status;
      while (digitalRead(8) == LOW) {
      }

    }

  }
  if (status == 1) {
    FadeOn(2000);
    FadeOff(2000);

  } else {
    digitalWrite(9,LOW);

  }
  Serial.print(digitalRead(8));
  Serial.println(status);

}

【实验二】可调档位灯

1.图形化编程块

2.代码块

volatile int bright;
volatile int click;

void setup(){
  pinMode(8, INPUT);
  Serial.begin(9600);
  click = 0;
  bright = 0;
  pinMode(8, INPUT_PULLUP);
}

void loop(){
  if (digitalRead(8) == LOW) {
    delay(200);
    if (digitalRead(8) == LOW) {
      click = click + 1;
      if (click == 6) {
        click = 0;

      }
      while (digitalRead(8) == LOW) {
      }

    }

  }
  analogWrite(9,(click * 51));
  Serial.println(click);

}
