Intent:
Control a Sony VISCA-compatible Pan-Tilt-Zoom (PTZ) Camera with an Arduino, if you're into that sort of thing.

Disclaimers:

• Last built and tested in 2015 using ~Arduino 2.1, so it's possible things have changed since then 🙏
• This code will make most programmer's / EE's eyes bleed. Despite that, I'm sharing it in case it saves anyone time & trouble!
• Developed and tested with a Sony EVID-70, but it should work with any camera using the VISCA protocol via RS-232.

Usage:
VISCA_Controller_v1_02.ino is the main file. All other files contain functions.
