Arduino 實作 :

CH5 MOOD CUE

CODE :
#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);
}

CH6 Light Theremin 

CODE :

int sensorValue;

int sensorLow = 1023;

int sensorHigh = 0;

const int ledPin = 13;

void setup()

{

  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()

{

  sensorValue = analogRead(A0);

  int pitch = map(sensorValue,sensorLow,sensorHigh,50,4000);

  tone(8,pitch,20);

  delay(10);

}

CH7 Keybpard instrument

CODE :


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

void setup()
{
  Serial.begin(9600);
}

void loop()
{
  int keyVal = analogRead(A0);
  Serial.println(keyVal);
  if (keyVal == 1023)
  {
    tone(8,notes[0]);
  }
  else if (keyVal >=900 && 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);
  }
}
