I just put together a costume project using a Wave shield. I don't need help with anything but since I bought everything from Adafruit I thought I'd share. Note that I'm new here so I don't know the forum etiquette.

The code is not very clean because it was recycled from a previous failed project that used more LED's. I used some creative looping to save text space.
- Code: Select all
#include <AF_Wave.h>
#include <avr/pgmspace.h>
#include "util.h"
#include "wave.h"
#define DEBOUNCE 20
#define swPin 14
int value = 255;
int ledpin[] = {18,19,6,7,8}; //5 output pins declared 1 used
AF_Wave card;
File f;
Wavefile wave;
void setup() {
byte i;
digitalWrite(ledpin[1], LOW);//Default off
Serial.begin(9600);
for (byte i = 2; i <= 5; ++i) {
pinMode(i, OUTPUT);
}
for (byte i = 1; i <= 5; ++i) {
pinMode(ledpin[i], OUTPUT);
}
for (byte i = swPin + 1; i <= swPin + 3; ++i) {
digitalWrite(i, HIGH);
}
if (!card.init_card()) {
putstring_nl("Card init failed!"); return;
}
if (!card.open_partition()) {
putstring_nl("No partition!"); return;
}
if (!card.open_filesys()) {
putstring_nl("Couldn't open filesys"); return;
}
if (!card.open_rootdir()) {
putstring_nl("Couldn't open dir"); return;
}
}
void loop() {
switch (check_switches()) {
case 2:

playfile(picker(0,1));
