Cameras can be used in numerous applications: survellience, hobbies, robotics, etc. They are very useful to see what is happening when a robot is moving on its own or even to just have fun with.
I got a UART camera to play around with and that I intend to stick on a robot. However, getting the code functioning on the camera was more difficult than I initially expected and there did not appear to be any good tutorials available.
I modified the code provided by Linksprite for their camera so that it will continuously take pictures rather than take one and stop. After all, if this camera is going to be used on a robot, it should be able to take more than one picture.
