Arduino IDE as simple oscilloscope (Arduino IDE 簡易示波器)

 Arduino IDE as Simple Oscilloscope 

使用的語法

• Serial.begin(115200);
• Serial.println(變數名稱);
• Serial.print(" ");

程式碼範例-單一變數

void setup() {
  Serial.begin(115200);
}

void loop() {
  for (int i = 0; i <= 250; i+=10)
  {
    Serial.println(i);
    delay(5);
  }
  for (int i = 250; i >= 0; i-=10)
  {
    Serial.println(i);
    delay(5);
  }
  for (int i = 0; i >= -250; i-=10)
  {
    Serial.println(i);
    delay(5);
  }
  for (int i = -250; i <= 0; i+=10)
  {
    Serial.println(i);
    delay(5);
  }
}

程式碼範例-多個變數

int Var1 = 0;
int Var2 = 0;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
}

void loop() {
  for (Var1 = 0,Var2 = 250; Var1 <= 250; Var1+=10)
  {
    Serial.print(Var1);
    Serial.print(" ");
    Serial.println(Var2);
    delay(5);
  }
  for (Var1 = 250,Var2 = 0; Var1 >= 0; Var1-=10)
  {
    Serial.print(Var1);
    Serial.print(" ");
    Serial.println(Var2);
    delay(5);
  }
  for (Var1 = 0,Var2 = -250; Var1 >= -250; Var1-=10)
  {
    Serial.print(Var1);
    Serial.print(" ");
    Serial.println(Var2);
    delay(5);
  }
  for (Var1 = -250,Var2 = 0; Var1 <= 0; Var1+=10)
  {
    Serial.print(Var1);
    Serial.print(" ");
    Serial.println(Var2);
    delay(5);
  }
}
