Hi, I am following along in the Halloween Pumpkin project, and adapting it to my sons Halloween costume. What I would like to do is replace the sensors in the original project, with a button that my son can press when needed, to play the sounds and turn on LEDs.
Are there any examples of code from other projects? Or does anyone know how I can alter the code from the halloween pumpkin project to fit my button idea?
Thank you.

The pumpkin project code has 5 different actions responding to 5 distance ranges from the sensor. Did you want to use multiple buttons, or simplify the code to have just one action?

Yes, Im looking to simplify the action, so that one button push, both plays a wav file and turns on the LEDs. Sorry if this is a simple question, Im new to arduino.

Re: How do I change the Halloween Pumpkin project from senso
The first step is to get the button wired up. Lesson 6 covers wiring and coding for buttons: https://learn.adafruit.com/adafruit-ard ... tal-inputs
You can eliminate the code in the loop() Just add a test for the button press and play a sound.
This code should turn on the leds and play one of 4 files at random. You can expand on that if you want.

Code: Select all
void loop()
{
if (digitalRead(buttonPin) == LOW) // button press
{
digitalWrite(eyeleds, HIGH);
int i = random(4); // select a random track to play
switch(i)
{
case 0;
playcomplete("HPYHALWN.WAV");
break;
case 1;
playcomplete("SCREECH.WAV");
break;
case 2;
playcomplete("GHOULLAF.WAV");
break;
case 3;
playcomplete("BOOHAHA.WAV");
break;
}
digitalWrite(eyeleds, LOW);
}
}

Thank you very much for this. I will give it a shot and let you know how it goes.

Re: How do I change the Halloween Pumpkin project from senso
So I have played around with the code and came up with this:
As you can see I swapped out the old sensor code for what you suggested, and fumbled through getting it to upload. Im sure its not 100% correct, and that is probably why Im getting weird behavior.
So, after successfully uploading the code, and testing the button. It will only play a few times before failing to play. Also since im only testing it, rather than soldering the button connections I am simply touching the wires from the bread board with a button setup to the ground and #9 pin on the WaveShield, and it plays without pressing the button.
Im sure there are a million things I did wrong. Ive attached a photo so that you can see how ive set things up. Hopefully you can see where Ive gone wrong.
Thanks again for your help,
Garret

Re: How do I change the Halloween Pumpkin project from senso
You have all your card initialization at the end of your loop. It should be in the setup as in the tutorial code.

After switching the order of the code its all working now. Thank you very much!!!
