Hi everyone I wanted a intervalometer ,but I don’t have money ,so I after watching a few tutorials I found this app :

I found lying around in my house a 3.5mm cable to 2.5 mm.

it works!!! but when I use the time-lapse it shots two pictures instead of one.

The theory that I have:

My cellphone outputs to much energy or signal .o for a longer period of time  forcing the camara to shoot twice.

I have a Moto G5 but I tried whit several older phones and it didn’t work.

I think this is the solution: http://bitshift.bplaced.net/en/dslr-remote/hardware/cable-a---opto-couplers.htm

but I don’t have  any soldering knowledge and I don’t know if I can buy that in my city.

If anyone knows how to solve this let me now.

The camera shutter is triggered using a TTL signal; that is a digital signal which is either high or low, off or on. Making it higher or adding more "power" will not change the logic. Check the settings on your camera and in the app. Is your camera set for continuous shutter? That would explain why you get multiple images for one trigger from the phone.

It depends on the camera you are dealing with, but with a recent Canon camera with WiFi, you can use the Canon Camera Connect app as a remote shutter.

 

And wired intervalometers are cheap; while the official stuff from the OEM is expensive, third party ones, such as the Vello ShutterBoss or the Neewer Timer Remote are considerably cheaper.
