DollyShield description:

The DollyShield is for DIY motion control for timelapse and videography. Controls a camera dolly.

Provides all elements necessary for a stand-alone user interface, an integrated and isolated camera connection, easy access to the hardware serial pins through a stereo jack, and an additional stereo jack connecting to pins D2 and D3 to allow for the use of encoders or limit switches. D2 and D3 are chosen for their association with hardware interrupts which increase the reliability of encoder or limit switch actions.
