    i m working on "Wireless surveillance system using zigbee".
    But i want to add external PIR motion sensor and wireless zigbee module with Arduino.
    The images are stored in SD card. but my goal is when the PIR detects any motion the image should be stored in memory card (Done in attached code)and then that image should be transferred through zigbee (Zigbee Tx is connected with Rx Pin0 and zigbee Rx is connected with Tx Pin1). PIR sensor output is connected with Pin7 of arduino.
    So what are the additions/modifications do i require for transmitting image on Pin1 in following code.

    I am using this code

    Re: Wireless Surveillance System using Arduino and Zigbee

    Also. Wrong forum.
    the Arduino programming typically happens in C (or rather C modules ("sketches") on top of the arduino framework).

    - you make mention of memory card, but none of your "hardware" seems to have any of this.
    - I'm not entirely up to spec on all the arduino compatible modules, but it doesn't look like that particular camera module has a data-interface, rather, it outputs the video on the RCA jack (composite video).
    - also, it appears you're using digital pin 13. Note you can't use this particular pin like the others, since it's usually got a built in resistor and led.


    Build up your arduino sketch in steps.
    write code to test the individual modules and to make sure you understand how to program them, then tie them all together.
    It's important to do it this way to make sure you haven't made a wiring problem.
    don't remove your test code, keep it in there but comment it out so you have it handy if you need to test again.
