I want to take some pictures with turntable which belt to an electric motor,after i take the picture i want to turntable  turn a angle,then i could make something like 360° image .
so what i need is a script to take the picture then give a signal to arduino to control the turntable to turn,then take the picture and turn again,until finish the whole 360°, something like that。
As long as you have some way to communicate with the arduino from the system that's running chdkptp, you should be able to do this using the method I described.

The details would depend on how you intend to communicate with the arduino.
OK i will try to do some test
Thank you

If it was me, I'd use a Lua script running on the camera to light the focus assist lamp after each shot. Then I'd use a phototransistor connected to the arduino to tell the arduino to index the turntable.  No PC or PTP required.

You could also close the loop by having the arduino tell their camera to shoot via a CHDK USB Remote signal.
Good idea !yes that the easy way
