Week 14, 12/11: Music Box 2

All the files for our music box can be found here: http://lauralippincott.com/musicbox

Here's the Sketchup file I have for us to start from. It has a cutout for each component, and interlocking box joints that require no glue or nails. We'll need to build a linkage to lift the lid, and a dancer to spin on the continuous rotation servo. Basel has composed a melody for us using the Pitches library.

#include "pitches.h"

// notes in the melody:
int melody[] = { NOTE_D3, NOTE_F3, NOTE_A3, NOTE_G3, 
NOTE_C3, 0, NOTE_C3, NOTE_D3, NOTE_F3, 
NOTE_A3, NOTE_D3, NOTE_F3, NOTE_A3, 
NOTE_G3, NOTE_C3, 0, NOTE_C3, NOTE_F3, 
NOTE_F3, NOTE_A3 };

// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = { 34, 20, 20, 25, 45, 20, 20, 30, 
40, 30, 55, 23, 56, 40, 35, 23, 67, 5 };

void setup(){
}

void loop(){
  for (int thisNote = 0; thisNote < 18; thisNote++) {
    int noteDuration = 1000/noteDurations[thisNote]; // one second divided by note duration
    tone(8, melody[thisNote], noteDuration);
    int pauseBetweenNotes = noteDuration * 1.30;
    delay(pauseBetweenNotes);
    noTone(8); // stop the melody
    delay(1000); // pause for a second
  }
}

Week 13, 12/4: Music Box

1. Piezo Sensor: Phyllis

We're still having trouble getting readings from the piezo sensor, but the idea is that an initial knock will activate the box. Deliverables: datasheet, circuit diagram, detectKnock() function that has a boolean knockDetected.

2. Standard Servo: William

William's job is to build the linkage that translates the motion of the servo to the door lifting up. Deliverables: datasheet, circuit diagram, openDoor() and closeDoor() functions, linkage.

3. Photoresistor: Shiang

When the door opens, light will hit the photoresistor and activate the RGB LED. The photoresistor has a boolean for lightDetected. When the box is closed, lightDetected is false. When the box is open, the brightness of the LED will be inversely proportional to the brightness of the room. Deliverables: datasheet, circuit diagram, detectLight() function, global boolean.

4. Continuous Rotation Servo: Michael

The motor will spin a dancer clockwise during the day and counterclockwise at night. When the global variable lightDetected is false, the motor won't move. Deliverables: datasheet, circuit diagram, spinDancer() function.

5. Gyroscope: Marianna

The values for the XYZ of the gyroscope will be mapped to the RGB of the LED. Deliverables: datasheet, circuit diagram, readGyro() function, gyroXYZ[] array.

6. Piezo Buzzer: Basel

Basel is composing a melody for the dancer. It should be responsive in some way to the motions of the dancer via gyroXYZ[]. Deliverables: datasheet, circuit diagram, playMelody() function, melody.

7. Ping Sensor: Robert

An always-on ping sensor will deactivate the box when the viewer walks away. Deliverables: datasheet, circuit diagram, readPing() function.

8. RGB LED: Clarinda

The RGB LED will be influenced by both the photoresistor and the gyroscope. The RGB values will be stored in an array, and mapped to the XYZ array of the gyroscope. Deliverables: datasheet, circuit diagram, changeColor() function, global ledRGB[] array.

The things we'll need to work on collectively are the master circuit diagram, the code architecture, and the box. I think we should 3D print the box. This is what I have so far in SketchUp; we can figure out how to add holes to mount all the components and Arduino in it. 

I'm excited about this, hope you guys are too! We'll only end up with one, but with good design and documentation, everyone could easily make one of their own.
