I will introduce myself first as i myself get annoyed with others that just ask a question and 'run'.
Firstly my name is Ben Bryden, profession: Cad/Cam engineer. I'm currently under taking a time lapse slider project for a 70d dslr camera, being purely mechanical i have next to no knowledge of electronics or programming these boards, hence this question.
I'm using a Arduino Uno - R3 board with RGB lcd shield kit.
I would appreciate if anyone had a program already written that i can use to generate the 'shoot - move - shoot' for perfect time lapse.
I.e. change the input variables that are displayed on lcd shield that controls the time the motor runs then a time delayed pause then trigger the camera shutter then run the motor again for the next move and repeat, so on.
If anyone would be some kind to answer this question it would be a major help, thanks.

How is the camera shutter triggered? Mechanically or electronically?
You haven't told us anything about your physical arrangements - such as how the camera is triggered, what system do you have for moving the motor, how is the movement powered - and probably many more issues.
There should be no difficulty doing what you want with an Arduino Uno but the details depend on the specifics of your setup.
If you already have any hardware that is controllable directly by an Arduino please post a link to the specifications.
If you have some of the physical system already constructed a phot would provide useful background info.
There have been many other Threads about camera control, sliders etc. Google should help you to find them if you restrict your search with site:arduino.cc
Your description "The trigger will be electronically controlled within the C++ code" doesn't really add anything to my existing knowledge - I had rather assumed that much. The important question is how to interface the code to the physical camera?
I think I have some of those stepper motors and similar stepper drivers.
What do you plan to do with the LCD shield - I don't have one of those. Can you post a link to its specifications?
So --- what do you plan to start with?
Have you attempted any code to do any part of the project? If so post it here (and PLEASE use the # button to enclose the code in code tags).
If you haven't started any code then you should study the examples that come with the Arduino IDE. There are probably examples for all the pieces you need.
To start with just make short sketches that do one thing such as move the motor, trigger the camera, manage timing (use some LEDs to give simple visual feeback). Don't try to combine things until you can get each separate piece to work.
Yes you are right about the interface it doesn't have one on that shield. I will have to find a shield that can interface to my camera body, unless you know of one on the market? I will research now.
INTERFACE
Computer Hi-Speed USB
Other Video output (PAL/ NTSC) (integrated with USB terminal), HDMI mini output (HDMI-CEC compatible), External microphone (3.5mm Stereo mini jack)
I suspect none of those is intended to operate the shutter.
Does it have a connection for a traditional cable release?
Does it have an Infra Red remote control for taking pictures of yourself or for eliminating camera shake?
I am not familiar with the 70d. It's been years. Perhaps it has a 3.5mm plug? If not, it is easy to Google. When I google I find more complex circuits. Only a resistor is needed in series, and not even that is required to function.
@sbright33, I imagine if the OP's camera had anything like that he would have mento=ione it in Reply #7. Perhaps the newer cameras are not as versatile as they were when you had one.
Almost every camera has either a wired remote shutter or IR or Radio. Read the manual, find out how pros trip the shutter remotely manually, then figure out how to duplicate that.
I think I would choose a wireless transceiver that has an onboard MCU with one or more GPIO pins. Choose one of the pins to be output and connect this to the remote shutter release, this would eliminate cables and make for a cleaner installation. I have set Zigbee pros up to to this at 1,000 meters for my Nikon DSLR.
You will need to spec more of the requirements for the slider for us to help.
