1  Using Arduino / Motors, Mechanics, and Power / Strongest Motor? on: July 17, 2013, 07:32:03 pm
I need a FAST strong motor for a 007 mod I'm building for my car using the arduino board and a motor shield. What do you recommend? Cheers

I'm building a tricked out 007 Challenger. Check out the site. http://dbl07.co/007_Challenger.php I need help developing some of the more complicated systems and I am offering a $100 CASH PRIZE to the person with the best solution (including code and schematics).


Edit: link corrected.

Got your Batman theme!
It is not much but here it is anyways

Code:
/* Pelle Jansen - 30-12-2012
 *Play Happy Birthday
 *
 * The circuit:
 * base of NPN transistor thrugh 500R(depends on transistor used) to pin 13,
 * Emitter of NPN transistor to ground
 * Collector to speaker negative
 * speaker positive to VDD
 * can also use mosfet.
 */
 
// includes and defines:
#include "pitches.h" // most used notes as defined frequencies

// constant var defenitions:
const unsigned char button=2;
const unsigned char spk=13;

// Variable and function defenitions:
int Batman[] = {
   NOTE_A3, NOTE_A3, NOTE_GS3, NOTE_GS3, NOTE_G3, NOTE_G3, NOTE_GS3, NOTE_GS3, NOTE_A3,
   NOTE_A3, NOTE_GS3, NOTE_GS3, NOTE_G3, NOTE_G3,NOTE_GS3, NOTE_GS3, NOTE_A3, NOTE_A3,
   NOTE_GS3, NOTE_GS3, NOTE_G3, NOTE_G3, NOTE_GS3, NOTE_GS3, NOTE_A3, NOTE_A3, NOTE_GS3,
   NOTE_GS3, NOTE_G3, NOTE_G3,NOTE_GS3, NOTE_GS3, NOTE_E4, NOTE_E4
};
unsigned char length=sizeof(Batman)/2;
// note durations: 4 = quarter note, 8 = eighth note, etc.:
int noteDurations[] = {
  8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 4, 4,8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 8, 4, 4, 4, 4};
unsigned char lengthDur=sizeof(noteDurations)/2;

// Set up the microcontroller
void setup(){
  Serial.begin(9600);
  Serial.println("Serial active! ");
  pinMode(button, INPUT_PULLUP);
}

// play the song
void play(){
  // check if there are as much notes as durations
  if (length != lengthDur){
    Serial.println("ERROR: note durations not equal to number of notes! ");
    Serial.print("Length of Batman: ");
    Serial.print(length);
    Serial.print("; Length of durations: ");
    Serial.println(lengthDur);
  }
  // iterate over the notes of the Batman:
  for (unsigned char thisNote = 0; thisNote < length; thisNote++) {   
  // to calculate the note duration, take one second divided by the note type.
  //e.g. quarter note = 1000 / 4, eighth note = 1000/8, etc.
  int noteDuration = 1000/noteDurations[thisNote];
  tone(spk, Batman[thisNote],noteDuration);
  Serial.print("Current frequency: ");
  Serial.println(Batman[thisNote]);
 
  // to distinguish the notes, set a minimum time between them.
  // the note's duration + 30% seems to work well:
  int pauseBetweenNotes = noteDuration * 1.30;
  delay(pauseBetweenNotes);
  noTone(spk);  // stop the tone playing:
  }
}

// main loop
void loop(){
  // play the song
  // to not repeat: move play() to setup() and remove delay
  play();
  delay(1000); // Slow repetition
}
I'm sorry I'm a noob, but what hardware would I use this code for? Be patient I'm learning

Is there a simpler cheaper way to do this?
but another card ?
Holy Hairballs Robin why didn't I think of that! Ha
I mean, how can I build something like this from scratch to play my theme song 007 in a loop without spending 150 on the whole rig  smiley-money Thanks for all your replies btw!

So I got a sweet Batman Birthday card that plays a short clip of the Bat Theme when I open it.  Then I cut the card open with my knife cause I wanted to see how they did it. So my question is I want to make something like this that has a simple trigger that will play one sound when the switch is opened, but so far the only thing I've seen is I have to buy a MEGA attached to a MP3 Shield etc and $150 later I have the same thing that this $5 card came with.
Is there a simpler cheaper way to do this?
Cheers

Im looking to recreate the effects that the International Spy Museum in D.C. has on display of their Aston Martin DB5. I can wire, and solder, but not to good with programing end. What parts list would you recommend to achieve the following:
push a momentary switch that will activate 2 linear actuators that push the headlights down and activate a group of LEDs that flash with the mp3 sound of guns firing. Then everything stops when the button is released. Cheers
