Arduino 入門 LED 閃爍實驗






int ledPin = 10; //定義數位 pin 10 介面

void setup()
{
pinMode(ledPin, OUTPUT);//定義LED為輸出介面
}

void loop()
{
digitalWrite(ledPin, HIGH); //ON LED
delay(1000); //延時1

digitalWrite(ledPin, LOW); //OFF LED
delay(1000); // 延時1
}

Arduino 入門 Hello World!




int val;     //定義變數val
int ledpin=13;   //定義數位介面pin 13

void setup()

Serial.begin(9600);  //設定串列傳輸速率為9600

pinMode(ledpin,OUTPUT);//設定數位13 為輸出介面
}


void loop()
{
val=Serial.read();   //讀取PC 發送給Arduino 的指令或字元
                         //並將該指令或字元賦予val

if(val=='R')   //判斷接收到的指令或字元是否是R

{  //如果接收到是R

digitalWrite(ledpin,HIGH); //ON 數位13 的LED。
delay(500);
digitalWrite(ledpin,LOW);  //OFF 數位13 的LED。
delay(500);
Serial.println("Hello World!"); //顯示「Hello World!」字串
                                      //於Serial Port Monitor 上

}     //end if   

Arduino Uno安裝設定















Arduino Uno板子正面照。















背面上印有"R3"。

USB cable連接板子與電腦後,Windows會出現新增硬體視窗
因為要自行指定驅動程式,所以選「不,現在不要」。


然後選從清單或特定位置安裝(進階)


只勾選「搜尋時包含這個位置」,按下「瀏覽」,

指向Arduino軟體解壓縮後的目錄下的drivers目錄。


然後就會開始安裝了。


安裝時,你可能要按下「繼續安裝」。


DRIVER安裝完成。


接下來,要找出Arduino板子被接到哪一個序列埠上。

雖然用的是USB連接線,其實是將USB模擬成序列埠。


首先到「Tools」-「Board」設定你用的是哪塊板子。
Arduino UNO

然後到「Tools」-「Serial Port」設定的com port 。
COMX

Arduino軟體提供一些寫好的程式範例,我們可以拿來測試看看。
請選「File」-「Examples」-「1.Basics」-「Blink」。

Messaging API作為替代方案

  LINE超好用功能要沒了!LINE Notify明年3月底終止服務,有什麼替代方案? LINE Notify將於2025年3月31日結束服務,官方建議改用Messaging API作為替代方案。 //CHANNEL_ACCESS_TOKEN = 'Messaging ...
