I found the need for a motorized camera slider. I wanted to build my own. After doing some web searches on the web I decided Max from Max Maker had the best solution, a motorized Arduino camera slider. Being very anxious to start the build, I ordered the camera slider, stepper motor, easy driver, and Arduino. After getting into it though, I found that the switch/arduino/stepper hookup diagram was missing on Max Makers instructables page. That made me decide, I would share my experience with you.
I do have the wiring diagram and some shabbily thrown together plans on my website.
