how do i trigger a digital camera when it arrives at a waypoint?

Posted by Neal Kelley on May 21, 2009 at 12:25pm
I want to have my ardu pilot tigger my camera when it arrive at the waypoint. I do not know much about programming so i am not sure how to do it. I want to get a micro relay and attach it to the ardu pilot and when the aircraft reachs a waypoint it will trigger the camera. I have taken apart my C913 kodak and have found the contact to trigger the camera. I have soldered wires to the contact and can now trigger the camera when i touch the two wires.. I wanted to purchast a micro relay and connect it to the ardupilot some how so it can trigger when it arrives at the way point. Any ideas?

    I flew today.. and took a few photos from my air craft. The problem I now have is that there is alot of vibration effecting the photo.. I am using a nitro engine..( tower .47 ) engine.. I am using a kodak C913 ( 9.3 MP camera ). Any Ideas on how to reduce vibration..?

    Thanks for the information. What I did was use a microservo and a Micro switch soldered to the wires coming from the camera button.. Works very good... I have the servor plugged into the retract plug on the reciever. So when ever I hit the retract button on my radio it triggers the camera. I guess the other question.. and i think i was not really clear in asking it is.... " how do I make the Ardu pilot trigger the camera when it gets to the way point. I am not a programmer and do not know how to tell it to do it in code. All I need the ardu pilot to do is move a servro back and fourth to triger the camera... when it arrives at the waypoint...... can any one help me with the coding part of that?

    Thanks

    You can use a Picoswitch and just tell the code to output PWM on a spare digital pin when it hits waypoints. Or, perhaps you don't even need the switch. Depending on the camera's internal voltage, you might just be able to wire it straight to the digital pin and set it high )+5v) when you want it to trigger.

    I suggest that you use a optocoupler. If you use a free digital output pin on your ardupilot and make the code switch on this pin on the waypoint you want.
