One of the things I bought is a small plastic pan tilt kit. I got it on Ebay. It didn’t come with the servos. But I still had some small Micro 9G servos that fit the kit. To try it out I hooked up the little servos to one of my Bajduinos. I then wrote a sketch to control the pan/tilt kit with a simple analog joystick. The kit is ideal to mount a small webcam on it. Well that was my original plan. But I recently bought the official Raspberry Pi camera board. The camera fits perfectly on the kit My goal is to control the pan/tilt kit over wifi through the Raspberry Pi and an Arduino. But that is a project that will take me some time. Need to learn some python first.
