Week12 劉柏廷

更新驅動程式，並檢察連接阜。

參考exmple 2-2 BUTTON 製作

///需要使用 10歐姆電阻

更新後的簡單程式碼

(當按下之後會發亮)

/*

void setup()

{

  pinMode(13,OUTPUT);

  pinMode(2,INPUT);

}

void loop()

{

   int result =digitalRead(2);

   if(result == HIGH) digitalWrite(13,HIGH);

   else digitalWrite(13,LOW);

簡易線路版本

 void setup()
{
  pinMode(13,OUTPUT);
  pinMode(2,INPUT_PULLUP);
}

void loop()
{
   int result =digitalRead(2);
   if(result == HIGH) digitalWrite(13,LOW);
   else digitalWrite(13,HIGH);

}

感光元件 使用

  Analog Input

/*

int sensorPin = A0;    // select the input pin for the potentiometer

int ledPin = 13;      // select the pin for the LED

int sensorValue = 0;  // variable to store the value coming from the sensor

void setup() {

  // declare the ledPin as an OUTPUT:

  pinMode(ledPin, OUTPUT);  

}

void loop() {

  // read the value from the sensor:

  sensorValue = analogRead(sensorPin);    

  // turn the ledPin on

  digitalWrite(ledPin, HIGH);  

  // stop the program for <sensorValue> milliseconds:

  delay(sensorValue);          

  // turn the ledPin off:        

  digitalWrite(ledPin, LOW);   

  // stop the program for for <sensorValue> milliseconds:

  delay(sensorValue);
