Schematic

The Core module detects if the Crash switch is pressed. The variable holding the status of the Crash switch will change to True if the switch is pressed and False if the switch is not pressed.

If True, the project will play the Happy Birthday music and light up.

If False, no music will play and the lights will be off.

Hardware Buildup

NOTE: When connecting sensor wires, push on the plastic connector and not on the wires. Pushing on the wire can damage them.

  1. Connect the Buzzer to the Sensor Hub on Pin 6/7
  2. Connect the Crash sensor to the Sensor Hub on Pin 4/5
  3. Grab the mCookie USBTTL or mBattery and Stack the mCookie Core on top.
  4. Stack the mCookie LED Matrix on top of that.
  5. Stack the mCookie Sensor on top of that.
  6. Plug in the MicroUSB cable to the mCookie USBTTL or mBattery to a computer.

Program

1. Connect mCookie Core to the PC with the USB Cable. Open the Microduino IDE.

2. Download the project file and unzip: File:Birthday Lamp X02.zip.

  • Using the Microduino IDE and go to File > Open... and navigate to the unzipped folder. Open the Birthday_Lamp_X02.ino file.

3. Select the board, processor and port:

  • Go to Tools > Board and select Microduino/mCookie-Core (328p)
  • Go to Tools > Processor and select Atmega328P16M,5V
  • Go to Tools > Port and select the available port

4. Upload the program by clicking on the right arrow icon on the top left of the window. Or under Sketch > Upload.

NOTE: If not using the default Core module included in the kits, please follow the selecting the board and processor guide.

Program Description

  • Function
    • "playNote()" Volume control
    • "colorSet()" Color control
    • "blink()" Judge if the key is pressed
  • Define pin
#define PIXEL_PIN     A0    //Digital IO pin connected to the NeoPixels (LED Matrix)

#define PIXEL_COUNT   6     //Number of NeoPixels in the LED Matrix

#define KEY_PIN       4     //Pin that the button (for play/pause) is connected to.

#define SPEAKER_PIN   6     //Pin that the buzzer is connected to.
  • Check switch and see if it is pressed.
    • Use file " key_get(KEY_PIN, 0)" to detect if the key is pressed. " KEY_PIN" is the pin that connects with the key, which can be change by users. "0" means triggering once pressing the key. "1" means triggering after you press and loosen the key.
    • Each time the key is detected to be "pressed", the True and False values of " play_pause " will change once. Therefore, you can control the music and light according to the values of "play_pause".
void blink()
{
  if (key_get(KEY_PIN, 0))  //Press the key 
  {
    delay(200);  //Shockproof 
    play_pause = !play_pause; // Status changes one time. 
  }
}
  • Light change (Red-green-blue-yellow)
    • "colorSet(strip.Color(R, G,B));" R, G and B are three primary colors. Users can change that according to personal needs.
add++;
if (add == 5)
add = 1;
if (add == 1)
colorSet(strip.Color(i * 10, 0, 0));
else if (add == 2)
colorSet(strip.Color(0, i * 10, 0));
else if (add == 3)
colorSet(strip.Color(0, 0, i * 10));
else if (add == 4)
colorSet(strip.Color(i * 10, i * 10, 0));
  • Play music
    • Save fixed notes and change the pitch in program definition.
int notes[] = {
  NOTE_C4, NOTE_C4, NOTE_D4, NOTE_C4, NOTE_F4, NOTE_E4,
  NOTE_C4, NOTE_C4, NOTE_D4, NOTE_C4, NOTE_G4, NOTE_F4,
  NOTE_C4, NOTE_C4, NOTE_C5, NOTE_A4, NOTE_F4, NOTE_E4, NOTE_D4,
  NOTE_AS4, NOTE_AS4, NOTE_A4, NOTE_F4, NOTE_G4, NOTE_F4
};

Debugging

Tweaking

DEBUG un-comment or comment to disable or enable debug mode.

PIXEL_PIN is the digital IO pin connected to the NeoPixels (LED Matrix).

PIXEL_COUNT is number of NeoPixels in the LED Matrix or ColorLED string.

KEY_PIN is the pin that the button (for play/pause) is connected to.

SPEAKER_PIN is the pin in that the buzzer is connected to.

Usage

Press crash switch, play birthday song and get lighted. The light will get brighter and brighter. Then press the switch once more, the music and light will be turned off.
