Step 8 Hook up the arduino

Hook up your arduino to the computer, copy and paste this code, and put it on your arduino.

If the code isn't visible below, I included a txt file of it so you can just download it that way.

Wavefile wave;

int inputPin = 8;               // choose the input pin (for PIR sensor)
int servoPin = 16;              // choose the input pin (for Servo)
int pirState = LOW;             // we start, assuming no motion detected
int val = 0;                    // variable for reading the pin status for motion sensor
int minPulse     =  600;  // minimum servo position
int maxPulse     =  2200; // maximum servo position
int turnRate     =  1800;  // servo turn rate increment (larger value, faster rate)
int refreshTime  =  20;   // time (ms) between pulses (50Hz)
int mouthchange = 6;  //checks to see if mouth position needs to be changed
int randNumber;   //random number variable to allow the choosing of which wav will be played


/** The Arduino will calculate these values for you **/
int centerServo;         // center servo position
int pulseWidth;          // servo pulse width
long lastPulse   = 0;    // recorded time (ms) of the last pulse

i get 9 error #include expects filename

sorry my key boards broke so some keys dont work, but yeah i compile this and get that error message is there anything i have to add, i need this by halloween.

Make sure you include Ladyada's AF_Wave library from her site for the Wave Shield
Also missing in the code here, there are 2 Include statements that are blank right at the top of the code. "Instructables doesnt like the "<>" symbols posted in the code and it dropped the information after the #include statement. I typed out the names of the symbols here before and after the information that is required.

The first one should be #include (less than symbol) AF_Wave.h (greater than symbol)
The second one should be "#include (less than symbol)avr/pgmspace.h
(greater than symbol)
It took me a bit to figure out (i'm new to arduino and not a programmer) looking at other examples of code lead me to change those two include statements
I loaded the code last night (without a servo hooked up yet) and the wav portion works no problem.

Cheers

Great Instructable. Anxious to re-task Mr. Skull!  When I try to verify the code on my Arduino, I get an error (looking for a particular filename). Any Ideas?

[samseide]

could be a library you are missing.  Take that error that you are getting and type it into google.  Whenever I had an error happen like that I was missing an arduino library I just had to download and throw into a folder.  Good luck!  Hope this helps!

[bill2009]

for some rason I can't see the code.  Is it posted directly somewhere?

[samseide]

it's posted in step 8 and is visible on my laptop here in firefox.  I had the same problem you were having when I tried to pull it up at my work.   I don't know why that is.  I'll send you a message with the code in it.
