i have speech on a audio track i want to make the mouths of these animatronics sync withe the speech.
there is one realy to control the mouth.

Halloween is a coming and i am working on updating some animatronics.
They run on cassette tapes at the moment and the boars are marked '87 so thought id update them.

I wish to run an arduino with either a SMD card on it with the audio files on there, and output the audio files.
The audio files will just be voice and the audio signal will go into the arduino which then out puts 5 volt signals to some transistors to gate to switch the 24V to the pneumatic relays to activate.

Should i use the wave shield to accomplish this?
or a simpler way you think? Possibly split the audio to the speakers and to the arduino input. using voltage references to trigger output to the transistor switches.

Any help would be great

sorry for the delay,

Here is how i am sending the emails with attachments. The code it actually in is alot bigger but the email sending is the same principal.

Code:

#include <Ethernet.h>
#include <SPI.h>
#include <SD.h>

byte ip[] = { 0, 0, 0, 0 }; // my ip
byte server[] = { 0, 0, 0, 0 }; // my smtp server ip
int time = 5000;
int wait = 2000;

it sends an email a few times then halfway through it seems to be cutting out and starting again.

I am using an Arduino Mega with a Ethernet Shield.

I have a program that datalogs and sends emails out every minute.
I can collect data and send out email once then on second loop through it freezes at connecting and just hangs there.

Any ideas?

Binary sketch size: 22274 bytes (of a 32256 byte maximum)

my program seems to not run with this memory used in sketch.

would this be the problem?

I can run other sketches on the same arduino with less mem used

perfect thanks

Idea:

User inputs in serial monitor "A3"
when read in hex it will be 0x41 and 0x33

I would like when read in HEX it will be 0xA3

how can i achieve this?

i know how to read the values and such and I'm reading one value at a time, so "A" then the "3"

thanks the volatile byte worked.

yes i know putting a delay in there is bad, in my actual program there is nothing like that.

thanks again

I am using a TIMER1 overflow interrupt,
I have written a quick code to test to see if i can update a variable with the interrupt as its being checked by a while statement.

Code:

   
    #include "TimerOne.h"
    
    byte FLAG = 0;
    void setup()
    {
      Serial.begin(9600);
      pinMode(6, OUTPUT);
      Timer1.initialize(1000000);        
      Timer1.attachInterrupt(callback);  
      Timer1.stop();
      
    }
    
    void callback()
    {
      digitalWrite(6, HIGH);
      delay(10);
      digitalWrite(6, LOW);
      FLAG = 1;
      Timer1.stop();
     }
    
    void loop()
    {
      Serial.println("SEND MESSAGE");
      Timer1.start();
      Serial.println("RECEIVING");
      while(FLAG == 0);
      FLAG = 0;
      delay(10000);      
    }
    

It doesn't notice the interrupt change in the FLAG status with :   while(FLAG == 0);

It does notice the flag change however if i put something in the while loop to check eg:

while(FLAG ==0){
Serial.println(FLAG, DEC);
}

Does anyone know why this is happening?
Doesn't  " while(FLAG == 0);" continuously check the state of FLAG anyways?

okay i figured that out too, here's a post Incase someone is wondering.
Sending Multiple Attachments

Code:

    Serial.println("connected");
  
                        client.println("HELO itismeletschat"); /* say hello (statement after helo is needed but irrelevant)*/
                          delay(wait); /* wait for a response */

                          delay(wait); /* wait for a response */

                        client.println("RCPT To: blank@virelec.com"); /* identify recipient */

                        encode();
                        datatxt.close();
                        delay(wait);
                        
                        datatxt =SD.open("meow.txt",FILE_READ);
                        [b]client.print("--$boundary\r\n");[/b]
                        client.print("Content-Type: txt; name=\"meow.txt\"\r\nContent-Disposition: attachment; filename=\"meow.txt\"\r\nContent-Transfer-Encoding: base64\r\n\r\n");
                        encode();
                        datatxt.close();
                        
                        client.println("."); /* end email */
                        client.println("QUIT"); /* terminate connection */
                        delay(wait); /* wait for a response */
            

           

If i want to send multiple attachments, do i have to use boundaries?
which i guess the next question is, what are boundaries and how do i use them?

oh! nevermind, i missed calling the function "encode();"

Everything is good. Thanks

Well i just tried that code again,
it decided to work this time, now i just need to send the contents of the txt file, it didn't have any contents.
but i can send a txt file.

This is the code i am running with the headers after data, which sends an email but no attachment just places those lines of code in the email body.

the results i posted above is when the "DATA" line is removed and the subject

can you use the code above that razor blade posted above for txt files?

i placed the code with .txt instead of jpgs

but when i run it i get this
