# 6.常用指令介紹

1.pinMode(pin,mode):指定第幾腳位，輸入或輸出\
例如:pinMode(13,OUTPUT):設定第13腳位為輸出

2.digitalWrite(pin,value):指定第幾腳位，HIGH或LOW\
例如:digitalWrite(13,LOW):設定第13腳位為低電位(0V)

3.analogWrite(pin,value):只支援PWM類比接腳(3,5,6,9,10,11)，0\~255\
例如:analogWrite(3,128):設定第3腳位為128，128為脈衝時間

4.delay(ms):延遲1毫秒時間\
例如:delay(1000):延遲1秒

5.Serial.begin(串列傳輸速率):設定每秒傳輸資料的速率

例如:Serial.begin(9600)

6.Serial.read():讀取序列阜收到的資料

7.Serial.print(資料)

例如:Serial.print(66)會顯示"66"

8.Serial.println(資料):用於換行
