I am using an arduino with adafruit audio shield to play six different audio files into a speaker that is connected. To reference each of these six audio files there is a respective button that is associated with each individual audio file. I also am using these buttons to activate a micro servo that is supposed to flick a needle at the speaker face once before the audio file begins. So basically my issue is I am able to use a button to activate the audio file and play through the speaker, and I am able to use a button to activate the micro servo, but I want to use one button to activate both in a timed fashion. I would like for a button to be pushed, the micro servo activate, a one second delay after the micro servo, then the audio file will begin to play. Here is my current code I am using for both the micro servo and the audio shield.
Audio files:
#include <FatReader.h>
#include <SdReader.h>
#include <avr/pgmspace.h>
#include "WaveUtil.h"
#include "WaveHC.h"
SdReader card; // This object holds the information for the card
FatVolume vol; // This holds the information for the partition on the card
FatReader root; // This holds the information for the filesystem on the card
FatReader f; // This holds the information for the file we're play
WaveHC wave; // This is the only wave (audio) object, since we will only play one at a time
#define DEBOUNCE 5 // button debouncer
// here is where we define the buttons that we'll use. button "1" is the first, button "6" is the 6th, etc
byte buttons[] = {14, 15, 16, 17, 18, 19};
// This handy macro lets us determine how big the array up above is, by checking the size
#define NUMBUTTONS sizeof(buttons)
// we will track if a button is just pressed, just released, or 'pressed' (the current state
volatile byte pressed[NUMBUTTONS], justpressed[NUMBUTTONS], justreleased[NUMBUTTONS];
// this handy function will return the number of bytes currently free in RAM, great for debugging!
int freeRam(void)
{
extern int __bss_end;
extern int *__brkval;
int free_memory;
if((int)__brkval == 0) {
free_memory = ((int)&free_memory) - ((int)&__bss_end);
}
else {
free_memory = ((int)&free_memory) - ((int)__brkval);
}
return free_memory;
}
void sdErrorCheck(void)
{
if (!card.errorCode()) return;

Servo:
#include <Servo.h>
Servo myservo; // create servo object to control a servo
* // a maximum of eight servo objects can be created*
int pos = 0; // variable to store the servo position
int button = 14; // The button will be on Pin 7
void setup()
{

pinMode(pos, OUTPUT);
pinMode(button, INPUT);
digitalWrite (button, LOW);
}
void loop()
{
* if (digitalRead(button) == LOW)*
* for(pos = 0; pos < 90; pos += 90) // goes from 0 degrees to 90 degrees*
* { // in steps of degree*
* myservo.write(pos); // tell servo to go to position in variable 'pos'*
* // waits 1s for the servo to reach the position*
* }*
* if (digitalRead(button) == HIGH)*
* for(pos = 90; pos>=90; pos-=90) // goes from 90 degrees to 0 degrees*
* { *

* }*
}
Any advice would be very helpful, this is supposed to be fully autonomous so rather than someone having to push the button then wait a second then push a different button to activate the speaker I would like all this to be done through the single push of a button.
Thanks in advance
