Update: Bluetooth Camera Remote

7 Jun

I have updated both the hardware setup of my camera remote as well as the software that is used to control the Arduino.

With regard to the hardware, I have soldered the optoisolator and capacitors to a small board. I also bought a remote cable for the Nikon D200 and connected it to my optoisolator, so that the setup can now be connected more easily to the camera.

The revised hardware part (the pins can be connected to the Arduino ports 13 and GND). Note that the setup can also be used for different brands of cameras by using a different adapter.

Here is a description of the circuit:

The simple circuit (note that the type of optoisolator given there is different to the one I used; could not change that in the software somehow).

With regard to the software, I updated my app with further modes for interval shooting and bulb (apart of the existing self timer mode). The new version of the app depends on Android 4.0 (ICS) in order to work properly, as I used the advanced number pickers that are not available in the older versions of Android.

The start screen of the App.

The interval shooting mode. You can pick the pause between the shots, as well as how many pictures you want to have taken (as the Arduino keeps track of time etc., the App can be closed after triggering the interval shooting).

I also pushed all the code to a Bitbucket repository with a small description of how to get this setup to work: https://bitbucket.org/boden/btcamremote/
