Description:
created a prototype that allows you to trigger the Teenage Mutant Ninja Turtle (TMNT) theme song when you shine a light on the photocell, and control the playback speed by spinning the bow-staff.
Components Used:
- Light Emitting Diode (LED)--green
- 10k resistor
- Arduino board
- Bread board
- Wires
- Photocell
- Piezo speaker
- Flashlight
- Electrical tape
- Some cardboard
- Pencil (a.k.a. - bo-staff)
- Donatello background printout
- Donatello action figure
Arduino Code:

}
void pause(int duration) {

}
void playSong() {
for (int thisNote = 0; thisNote < 33; thisNote ++) {
// play the next note:
playnote(notes[thisNote], durations[thisNote]);
pause(pauses[thisNote]);
}
// hold before repeating:
delay(1000);
}
void loop() {
lightval = analogRead(lightPin); //read the value from the photocell
if (lightval > 400) {
