Week 13 課堂練習

提醒同學們,明天12/2(一) 是我們互動技術概論第13週的上課。
(1) 請不要忘了帶 Arduino Starter Kit 的實驗設備到學校哦!
(2) 明大要上課的內容是 Project 05 06 07 哦! 同學們今晚可以預習一下。
(3) 我們上課的目的,是為了讓同學們在期末完成自己構思的創意作品,同學們可以邊上課邊思考哦!
(4) 明天同學們記得帶 9V 的方塊電池(25元-60元一顆), 還有找找家裡有沒有一些要用電池的廉價的玩具, 我們可以在學校享受動手改裝的樂趣!


Project 06
int sensorValue;
int sensorLow = 1023;
int sensorHigh = 0;
const int ledPin = 13;
void setup() {
  // put your setup code here, to run once:
pinMode(ledPin,OUTPUT);
digitalWrite(ledPin,HIGH);
while(millis()<5000){
  sensorValue = analogRead(A0);
  if(sensorValue > sensorHigh){
    sensorHigh = sensorValue ;
  }
  if(sensorValue < sensorLow){
  sensorLow = sensorValue;
  }
}
digitalWrite(ledPin,LOW);
}
void loop() {
  // put your main code here, to run repeatedly: 
  sensorValue = analogRead(A0);
  int pitch = map(sensorValue,sensorLow,sensorHigh, 50,4000);
  tone(8,pitch,20);
  delay(10);

}

Project 07

int buttons[6];

int notes[] = {262,294,330,349};

void setup(){

  buttons[0] = 2;

  Serial.begin(9600);

}

void loop(){

  int keyVal = analogRead(A0);

  Serial.println(keyVal);

  if(keyVal == 1023){

    tone(8, notes[0]);

  }

  else if(keyVal >= 990 && keyVal<= 1010){

    tone(8, notes[1]);

  }

  else if(keyVal >= 505 && keyVal <= 515){

    tone(8,notes[2]);

  }

  else if(keyVal >= 5 && keyVal<= 10){

    tone(8,notes[3]);

  }

  else{

    noTone(8);

  }

}

Project 05

#include <Servo.h>

Servo myServo;

int const potPin = A0;

int potVal;

int angle;

void setup(){

  myServo.attach(9);

  

  Serial.begin(9600);

}

void loop(){

  potVal = analogRead(potPin);

  Serial.print("potVal: ");

  Serial.print(potVal);

  angle = map(potVal, 0, 1023, 0, 179);

  Serial.print(", angle: ");

  Serial.println(angle);myServo.write(angle);

  delay(15);

}
