Hey there,
I would like to build a sensor that turn an analogue camera on/off. This perhaps involves an arduino.
That would be great if I could get some advice on this !!!
Eventually, I would aim at bulding one that only switches on when the right amount of light is necessary to film.
Thank you in advance for your suggestions!
Best

arduino and a servo or small solenoid to depress a shutter could work. Google for kite flying and aerial DIY cameras, they quite often have little setups to control cameras. If you want it to work wirelessly there’s Xbee communication which are some extra electronics you need to buy.
If you don’t want to code, a simple kit like SAM labs can also do wireless communication, and is quite fun for beginners.
Thank you Karl!
Have a look to see if your camera has a remote port, and if anyone has documented a way to use that as an easier input.
A photodiode can be used to sense light onto an analog pin (you reverse bias the photodiode and put a current sense resistor to ground to sense the voltage on the diode side)
Figure out how the remote works (or potentially open the case and look if it’s a mechanical or electronic button) and probably fire that via a small transistor eg mosfet or something more appropriate
Enjoy
