[Arduino]Day6-超音波感測器

下面範例是計算出距離後，如果距離大於100,就顯示其中一顆LED，沒有就另一顆亮

int ECHO_Pin=4;  // ultrasonic ECHO
int TRIG_Pin=5; // ultrasonic TRIG
int Near_LED = 9;
int Far_LED = 10;

void setup()
{
  Serial.begin(9600);
  pinMode(ECHO_Pin, INPUT);
  pinMode(TRIG_Pin, OUTPUT);
}
void loop()
{
  digitalWrite(TRIG_Pin, LOW);
  delayMicroseconds(2);
  digitalWrite(TRIG_Pin, HIGH); // Pulse for 10 micro sec to trigger ultrasonic detection
  delayMicroseconds(10);
  digitalWrite(TRIG_Pin, LOW);
  int distance = pulseIn(ECHO_Pin, HIGH);  // Read receiver pulse time
  distance= distance/58;   // Transform pulse time to distance
  Serial.println(distance);   //Output distance

  if(distance > 100)
  {
    digitalWrite(Far_LED, HIGH);
    digitalWrite(Near_LED, LOW);
  }else{
    digitalWrite(Far_LED, LOW);
    digitalWrite(Near_LED, HIGH);
  }
  delay(50);
}

[Arduino]Day5-Read_GPIO-投票機

利用讀取GPIO做投票機功能

按下按鍵，對應LED亮起

注意按鍵跟LED都要經過電阻接地

//投票機

int YesLed=10;
int NoLed=9;
int YesPin=7;
int NoPin=6;
int Yes;
int No;

void setup() {
  // put your setup code here, to run once:
pinMode(YesLed,OUTPUT);
pinMode(NoLed,OUTPUT);
pinMode(YesPin,INPUT);
pinMode(NoPin,INPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  Yes = digitalRead(YesPin);
  if(Yes == LOW)
  {
    digitalWrite(YesLed,LOW);
  }else{
    digitalWrite(YesLed,HIGH);
  }
  No = digitalRead(NoPin);
  if(No == LOW)
  {
    digitalWrite(NoLed,LOW);
  }else{
    digitalWrite(NoLed,HIGH);
  }
}

[Arduino]Day4-傾斜開關-結合蜂鳴器

手邊的傾斜開關，又叫滾珠開關，英文名稱HDX 2801 double ball bearing vibration

運作原理可以參考下面連結的網頁
https://sites.google.com/a/jbps.ttct.edu.tw/zhi-ben-guo-xiaoarduino-yan-xi/di-shi-san-ke-qing-xie-kai-guan-led-deng-pao

型號HDX-2801
https://world.taobao.com/item/36393326058.htm

int Buzzer = 7;//蜂鳴器腳位
void setup()
{
  pinMode(8,OUTPUT);//設定LED腳位
  pinMode(Buzzer,OUTPUT);//
}
void loop()
{
  int i;
  while(1)
  {
    i=analogRead(5);// 讀取ADC 5的數值
    if(i<200)//如果小於 512（2.5V）
    {
      digitalWrite(8,HIGH);//亮LED
    }else{
      digitalWrite(8,LOW);//滅
      for(i=0;i<120;i++)//製造一個頻率
      {
        digitalWrite(Buzzer,HIGH);//發聲
        delay(1);//delay 1ms
        digitalWrite(Buzzer,LOW);//無聲
        delay(1);//delay 1ms
      }
    }
   }
}

[Arduino]Day3-Buzzer

蜂鳴器只有正負兩隻腳位
正給電就會發出聲音，
必須製造高頻頻率，才會是人耳較能接受的聲音
如果沒有高頻，直接給3.3V，則只有通電瞬間一小聲"波"就沒聲音了。





int Buzzer = 7;//蜂鳴器腳位
void setup() {
  // put your setup code here, to run once:
  pinMode(Buzzer,OUTPUT);//
}

void loop() {
  // put your main code here, to run repeatedly:
  unsigned char i,j;
  while(1)
  {
    for(i=0;i<120;i++)//製造一個頻率
    {
      digitalWrite(Buzzer,HIGH);//發聲
      delay(1);//delay 1ms
      digitalWrite(Buzzer,LOW);//無聲
      delay(1);//delay 1ms
    }
    for(i=0;i<150;i++)//製造另一個頻率
    {
      digitalWrite(Buzzer,HIGH);//發聲
      delay(2);//delay 2ms
      digitalWrite(Buzzer,LOW);//無聲
      delay(2);//delay 2ms
      }
   }
}

[Arduino]Day2-ADC-PWM

由ADC讀取電壓
並將數值經由PWM丟往LED

ADC腳位在A0，接到可變電阻的輸出腳位
Arduino的D11可兼做PWM，接到外部LED就可以顯示亮滅
用analogWrite就可以寫入PWM


int potpin=0;
int ledpin=11;
int Pot_Value=0;
void setup() {
  // put your setup code here, to run once:
  pinMode(ledpin,OUTPUT);
  Serial.begin(9600);
}

void loop() {
  // put your main code here, to run repeatedly:
  Pot_Value=analogRead(potpin);
  Serial.println(Pot_Value);//一邊將數值往序列埠顯示
  analogWrite(ledpin,Pot_Value/4);//對Digital腳位寫入PWM
  delay(10);
}

[Arduino]Day1-安裝與Hello world

1.手邊的Arduino是UNO-R3
接上USB就能自動抓到驅動

2.官網
https://www.arduino.cc/
到download抓開發軟體，選just download即可
https://www.arduino.cc/en/Main/Donate
目前版本
1.6.9

3.硬體設定
在工具列->工具->板子，選擇UNO

4.第一個練習 Hello world
int input_char;
int ledpin=13;
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);//設定鮑率
  pinMode(ledpin,OUTPUT);//設定pin13為輸出，因為他接在LED
}

void loop() {
  // put your main code here, to run repeatedly:
  input_char=Serial.read();//讀取串列埠
  if(input_char=='R')//如果收到'R'
  {
    digitalWrite(ledpin,HIGH);//將Pin13設定High，亮LED
    delay(500);//Delay0.5秒
    digitalWrite(ledpin,LOW);//將Pin13設定Low，滅LED
    delay(500);
    Serial.println("Hello World!");//顯示Hello world
    }
}

5.打勾邊譯

6.右邊箭頭上傳

7.工具列->工具->序列埠控制器
叫出序列埠控制器
打入大寫R，按傳送，就可以看到LED亮，滅，序列埠監控出現"Hello World!"
