Project: NIME, Team 11

 NIME TEAM 11

For this project, I wanted to create something akin to a piano keyboard. The goal was to play a range of notes with the button and use the instruments attached to the fan on the servo to produce background noise in addition to the notes being played.

So for the notes I chose the main ones from the song Runaway by Kanye West. It features a multitude of E sharps, C sharps, etc. I put those frequencies into an array in the IDE and allowed it to be played in full at the press of a button. I wanted to be able to cycle through them somehow but couldn't exactly figure out the code for that in time so I just settled for the whole range at one click of a button. The servo moves when turning the knob on the potentiometer. As it moves, the bells stringed to it jingle off the board and each other to produce a jingling sound in the background of the notes.

  // put your setup code here, to run once:

  CircuitPlayground.begin();

  Serial.begin(9600);

  delay(1000);

  //servo code

  myServo.attach(10); //A3

  pinMode(4, INPUT_PULLDOWN); //left button

  pinMode(5, INPUT_PULLDOWN); //right button

}

void loop() {

  val = analogRead(potpin); // gets the value of the potentiometer 

  val = map(val, 0, 1023, 0, 180); // converts it ton a number usable by the servo

  if(millis() > timer + 15) {

    if(val == 0) inc = 1;

    if(val == 180) inc = -1;

    myServo.write(val); // the servo is set to the stored value from the potentiometer

    val += inc;

    timer = millis();

  }

  

  if(digitalRead(5)) { // checks if button is clicked

  for(int i = 0; i < 23; i++) { // when button is clicked it loops through until it hits 23    CircuitPlayground.playTone(notes[i], 500); // plays the notes in the notes array

    }

  }

}

Do you think the enclosure being better crafted would enhance the experience and would there be a better way of stringing the bells onto the servo fan?
