I've been trying to build an Arduino UNO controlled Camera using two servo motors that points in the direction of an object with a certain tag.
Here's an Example: A camera is on the sideline of a gym, and the players are running around. One player has a portable GPS piece attached to him, and the camera should point in the player's direction in order to capture the player's movements along with his background.
A few questions: Would I use two different compasses in order to both record the direction and point the camera in this direction? Or would I use a GPS for the player and somehow convert the streaming data into compass direction(in which the camera will point)?
In a way, what combination (Player-Camera) would I use (if I need a combination), a GPS-GPS, GPS-compass, or compass-compass?
Do I actually need two location devices or just one?
