28BYJ-48 based pan and tilt for sensor scanner

thingiverse

I'm getting bizarre sensor readings when working with servo motors, and I suspect a clash within the Atmel interrupt domain since both servo libraries and sensor libraries utilize interrupts, although I'm not entirely sure about this theory. To resolve this issue, I created a pan-tilt system based on either the 28BYJ-48 or the MP35HA31 stepper motor set up in a counter-rotating configuration. The 28BYJ-48 used for panning has noticeable backlash, and my unit had its fair share of it. To eliminate this problem, I designed a bungee cord using a rubber band and some wire terminals which I attached to keep the system under tension and prevent looseness. It might be excessive, but the system employs two 688zz bearings that snap into place within the provided recesses. Initially, the design called for one stepper motor for tilt operations, but upon testing, it became apparent that two motors were weak and would miss steps at speed due to wire tension.
