DIY Camera SLIDER (Part 1) – Figuring out the ELECTRONICS | 2-axis MOTORIZED

In this series I embark on building a 2-axis motorized camera slider with sliding and panning of the camera. The slider will be controlled by a Arduino NANO and two NEMA17’s driven by a4988’s. The plan is to get this on a battery power supply so it can be used outdoors. In this first part I figure out roughly how the design is going to be and how to hook up and program the electronics so it can be controlled like intended.

First of you have the wiring diagram:
