ArduCam problem - DIY Telecine

Hello Forum,

I'm completely new to Arduino. I want to develop a telecine machine, like an optical printer, using an old 16mm projector. The idea is to replace its original motor with a step by step, activate a LED in place of the lightbulb and take a picture with an Arducam before advancing a frame, and so on until I have a digital file for each frame on the film. My first problem, however, is an Arducam I bought. I have plugged it to an Arduino Uno R2 and uploaded the examples, but I cant get any signal, although the LCD display is working. Any ideas? Any help would be useful. I have an Arducam Rev.C, an arduino UNO R2 and a OV5642 camera module.
