I've had some recent success working with a 3.3V arduino pro, a camera module and SD memory so I thought I would share what I have so far to see if anyone has done something similar.
My end goal is to take pictures periodically and geotag them, putting gps cordinates in the exif section of the jpeg.
This is the camera module - http://www.sparkfun.com/commerce/product_info.php?products_id=9334
Letting this run in a loop (see sketch below) I was able to take 100pictures, storing them on SD without an issue.  
There is a boilerplate EXIF header added to each JPEG until I figure out how to add GPS data that I will be reading from an attached module.
The software to interface to the camera module is a modified version of

The software to interface to the SD card is

This is the library that goes along with the sketch which is a combination of the above two with some modifications

The module for interfacing to the camera was modified to work with an attached SD card.  For SD pin connections you might want to check out this thread - http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1235125412

Note that with the arduino pro (pictured) since it operates at 3.3v you won't need to step down the voltage.

In addition to the SD card and the camera an LED is connected to pin 2 which is what is used to report ERRORS (see SDCameraC328.h for a long list of error codes..)

The module is hard-coded to write picture0001, picture0002, etc. every time a snapshot is taken.

Here is the prototype:

And here is an example picture feature my very dark work area (yeah the camera isn't that great..)

Code: [Select]

#include <SDCameraC328R.h>

void blink(int times);
void getJPEGPicture_callback( uint16_t pictureSize, uint16_t packageSize,
           uint16_t packageCount, byte* package);
#define ledPin 2
SDCameraC328R camera;

void setup()   {                
   Serial.begin( 57600 );
   blink(camera.InitializeSD());  // setting up the SD will result in images written to an attached SD card

   blink(camera.initial( SDCameraC328R::CT_JPEG, SDCameraC328R::PR_80x60, SDCameraC328R::JR_640x480 ));
   blink(camera.setPackageSize( 100 ) );
   blink(camera.setLightFrequency( SDCameraC328R::FT_50Hz ));

   // Let camera settle, per manual

void loop()                    
               blink(camera.snapshot( SDCameraC328R::ST_COMPRESSED, 0 ) );
               blink(camera.getJPEGPicture( SDCameraC328R::PT_JPEG, PROCESS_DELAY, &getJPEGPicture_callback) );


void blink(int times)
 if (!times) return;
 while (1) {
   digitalWrite(ledPin, HIGH);   // set the LED on
   delay(200);                  // wait for a second
   digitalWrite(ledPin, LOW);    // set the LED off
   delay(200);                  // wait for a second

void getJPEGPicture_callback( uint16_t pictureSize, uint16_t packageSize, uint16_t packageCount, byte* package )
  // if not writing to an SD card do something with the image data here..


You look like some evil genius in the picture XD
On the other hand, Pretty neat stuff, I didn't even know the arduino was capable of such things :O


lol yeah that's attacking the camera with a can of compressed air

Great job,

I am also involve in a similar proyect, but i am pretty new in arduino, so i am so so lost.

I use arduino duemilanove, a microSD (libelium), and the C328 camera. Could you show me how do you save the image in the SD?

I used your code and it seems to work, because when i open the serial windows, a sequence of symbols is wrote there, but the led only have light when i open the serial. May be since i didn´t do anything with the data (such as you propose in the comment at the end of your code, eg, save it in the SD), the sketch is waiting to do something...

And i neither know how to use Processing to see the image...

So any help will be very useful to me.

Thanks for your help!


since posting this originally I've managed to add geo-tagging to captured images using a LS20031 gps module.  details posted here  - http://jarv.org/sdcam.shtml


Thanks for the link. Looks like a great project.
I will try to learn about how it works.


I am trying to reproduce your project but compilation of your sketch giving me a lots of errors:

I am using "Adruino Duemilanove" and I get your latest code from jarv_org/sdcam.shtml


what version of avr-gcc are you using?



I have got exactly the same error messages as Posox while compiling the program with AVR-GCC 4.3.4.
Did anybody find our mistake ?


I think this is terrific and am looking at following your lead.
First question though -the camera
Nowhere does anybody give the resolution in megapixels. The photo of you looks a bit grainy but the one on the first site mentioned looks much better.

I'd like to start off with a decent camera image if I am going to spend the time

What would you use if you were to do it over?


@tytower - thanks! the max resolution is 640x480.  check out http://jarv.org/sdcam.shtml for what I ended up doing with it eventually.  It worked out well but I don't have any future plans beyond what I've done so far.

@stan49 - PB2 is just the pin number for the board, should be grabbing it from the include files. Not sure what is going on there with the arduino project.  Maybe try the project from http://jarv.org/sdcam.shtml to see if you get better results?

Yes jarv I saw that before and liked the idea .

My question more concerned the resolution of the images .
Is there a sample of what you shot over the park ?

[glow]If you were doing it over[/glow] would you use the same camera [glow]or seek a better one?[/glow]


yeah check out the flickr set here -> http://www.flickr.com/photos/43574582@N05/sets/72157622621272658/

quality is not that great, i'm not sure what i would use the camera for given the low quality.  With digicams as cheap as they are which can be controlled with a relay I don't know how useful it is unless you are interested in direct image manipulation.
