Hello and help!
I am trying to use my new TTL serial camera for a project that is due on Thursday. I want to use the motion detect function to activate a servo. I checked the camera and adjusted the settings using the CommTool, and wired the camera to the Arduino, but I keep getting "no camera found." I checked and redid all my connections; I also checked to make sure I had imported all of the libraries I need. I'm not sure what else to try. A photo of the wiring is attached (the violet wire is TX) and the code is below. Please help! Thanks, Alix
