Thank you for your replies and email.  Unfortunately, I have limited experience with Arduino and electronics alltogether.

Stereo usually only uses two cameras, is this for robotics use?

You are correct, but the build is for stereo lenticular photography, which requires more parallax than traditional two-view stereo cameras.

Perhaps you will want a shield that can control four. Or you could get external stepper drivers (not a shield) and run wires to them.

I searched for Arduino Uno motor shields for more than two stepper motors, but couldn't find any. 


I have decided to go another simpler route: two stepper motors w/ timing pulleys and belts.  With that said, I don't believe I'll be needing to hire anymore.

Everyone on the Arduino Forum is always helpful and I appreciate it a lot!  Thanks again!

Hi all,

I am interested in hiring an Arduino programmer to assemble and design a sketch, which controls four stepper motors using one proximity sensor and displays the distance.

The project is to develop a multi-camera rig for stero photography.

The purpose is to control the angle of multiple cameras that are each attached to a stepper motor in a single row.  The stepper motors angle calculations are based on the serial output by the centrally-located proximity sensor.  So the closer the detectable object, the greater degree of angle.  I assume a trigonometry sketch will likely need to be incorporated.  Also, the precise degree of movement will require the stepper motors to be setup with microstepping.

I can provide the parts, which currently includes Arduino Uno, Adafruit Stepper Controller (http://www.adafruit.com/products/81), Maxbotic Range Finder (https://www.sparkfun.com/products/9491), etc.  The items will be shipped with a return box and label for convenience.

Please email me at peterson.ryan.t@gmail.com with any bids, questions, and/or additional parts (e.g. display model, stepper motor model).

Sincerely,

Ryan Peterson
