Rocket Payload help!

Hi all, I am in need of some help... i have never used arduino, and i have a rocket payload due in a week. If anyone could help me that would be great

This is the arduino board i am using: https://www.sparkfun.com/products/10889 I want my video camera which is this one: https://www.sparkfun.com/products/11171 to turn on when the light sensor (attached to board) senses light. I also need the accelerator which is this one: https://www.sparkfun.com/products/9652 to record the acceleration during launch. Oh, and how do i attach the battery?

I honestly have no idea what i am doing, how to program it or anything. So anyone who knows how to do this could PLEASE help me!

The page you linked to for the camera says this:

If your application is remote controlled, the module can also be powered and controlled from an open channel on your RC receiver.

Having your Arduino read a value from an LDR and generate a servo output signal is a doddle.

I don't know where you are going to log the acceleration data [u]to[/u], or how often or for how long. Perhaps you could include an SD card that the Arduino can write to?

its not remote controled or i don't have access to it

This isn't a doddle of a project if you have waited this long and have prepared this little.

Peter is right, you have no where to record the accelerometer data.

You say nothing about powering all of this.

I assume your payload has weight and size limits.

chengin: its not remote controled or i don't have access to it

What's this comment about?

@PeterH- My guess would be that there is some sort of delay between packaging of the payload in the launch vehicle and launch time (such that payloads have to come "on" at the right time) and that OP will not have RC or physical access to the payload in that period or RC access during flight.

Have you tried googling your question in the form of keywords?

Like "Arduino, camera, accelerometer, rocket, payload" ?

It's been done....lots of times. Tons of info, posts, photos, videos & write ups on how they did it.

There is an interesting rocket project here http://code.google.com/p/android-scripting/ - about halfway down the page. It may suggest a more practical solution.

The OP has already said that the video needs to be enabled based on light levels and so far nothing mentioned has required remote control, so I suspect the reference to 'remote control' was based on a misunderstanding of Reply #1.

You might be right. We'll probably never know.

Hi all so i am making a rocket payload
This is the arduino board i am using: https://www.sparkfun.com/products/10889
I want my video camera which is this one: https://www.sparkfun.com/products/11171
to turn on when the light sensor (attached to board) senses light.

So, the sketch of what would be attached to what is attached (sketch.jpg)
My code is also attached (elizC)

I am asking if this will work so that when the light sensor senses light the camera will be turned on is my code and sketch correct?

thanks :slight_smile:

for(angle = 0; angle > 180; angle++) {
     camera.write(angle);
     delay(10);  // may need to tune this if takes too long
     // also - may need to tune the angle > 180 above  
  }

If all this is doing is pressing a shutter-release, why not simply camera.write(180);, and forget the 1.8 second long for loop?
