I recently purchased a chinese 140mm rotating plate for displaying watches etc.
The switches control speed, an automatic reverse, and direction.
Holding down the the left/right direction button will stop the rotation, after about 3 seconds.
What I want:
Replace the current controller with a controller that gets triggered by a camera remote button to rotate about 10 degrees and stop, That's when I take a photo of a miniature bottle, which triggers the next 10 degree rotation, for a total of 36 pictures.
I have 1500 of these miniatures, so this will take me some time correlating these photos for 360 spin videos.
I removed the platter, and saw that the motor is a 28JBY-48 stepper motor.
The ULN2003 will fit in where the commercial board is, so it should be easy to replace it, and add a few support posts
So now I need some help with an Arduino Uno to program the ULN2003 board to rotate this stepper motor 10 degrees, then stop, until I'm ready to take another picture.
I take it that this Arduino board could be set up to remotely control the camera as well, so I could have a cup of tea while doing this 360 spin thingy on each of these miniature bottles
The ULN2003 will fit in place of the original, or it could go in the AAA battery compartment
There's also a compartment for an 18650 3.75V 3800mAH battery, which I will use to drive the ULN2003
Then I would place the Uno into a box that would sit underneath the rotating table (with power supplied by an adapter, and suitable cable for the remote camera trigger)
The combined units will then sit in a lightbox (custom designed by me, of course)
Can anyone give me some pointers on how to program this?
