Cameras and video cameras are more and more dominant in everyday life. Just think of the incredible amount of security cameras you see every day or the millions of hours of videos on Youtube. As we use video cameras and other image capture devices every day, the desire to put down these gadgets seem only natural. That way you can get a much steadier and clearer picture, and you are also not bound to it locally, you can
But a camera just standing there won’t be sufficient for many users on its own. In many cases a camera stand that can rotate the camera will be much more satisfying and useful.
My goal was to design and implement a possible way to control a camera stand that can rotate a camera or video recorder fixed to it around two axes, by using two stepper motors.
The main microcontroller is prepared to receive RS-485 differential signals, which is used in the DMX512 standard widely used in lighting applications. The microcontroller should then set the position of the camera according to the received signals. This way the cameras can be easily synchronized with lighting systems, providing the user with a wide range of various opportunities.
Designing a converter that can send out RS-485 signals from the USB port of a PC for testing was also part of the task, but this part will not be introduced in this thesis.
