Hello, I am trying to have an arduino uno control 2 cameras and ensure that they constantly stay on and constanlty record. I have wired the arduino to internal parts of the camera such as the rec button, the power button, an internal power line and i have setup a LDR to the blinking LED on the camera that flashes when it records. I have had a lot of help with the software and I believe it was working fine; but it has sat in my basement for a few years due to having kids and work, but I am trying to get it back up and running now so I can attach these to a weather balloon this Sunday. I have powered it up but it seems like it is only taking the reading of the blinking LED on the camera for a split second but I would like it to monitor the blinking LED for a few seconds (perhaps anywhere from 5-10) and if the LED does not come on I would then like it to send a signal to the REC Button to record; but like i said it seems to just be taking 1 reading and if it happens to take that reading while the LED is blinking and in the off state it hits the REC button. any help would be GREATLY APPRECIATED. Like I said I don't really know what I'm doing here so if i have left out any information that you may need just let me know. Also I can provide pictures or video or anything you may need or we could even video conference if that makes it easier. Please let me know.
