Hi, im fairly new to arduino and im not the best at coding.
I am trying to build a project but I have no idea on how to start.
Id like to have a dslr camera track someone who is wearing a bracelet.
I was thinking two gps modules/ arduino (One for bracelet, one for camera mount)
Then a stepper motor and a 3d printed gear to will turn the camera. I have a rough concept of how the electronics can be wired, but my problem is Ive got no clue how to code it....Any tips? Thanks!
Also Ive never worked with gps modules so ive got no clue how to use them, maybe this is a basic build that im overthinking? I hope so
thanks again!

We are left to guess how far away the camera and bracelet are.

And as to whether its outdoors or indoors.

One of the keys to sucess in a project is beaing able to cleary describe what it is you are trying to do.

maybe i can offer some asistance,

you will have to set up your cammera with some sort of movement operation, if you just want left to right movement then you can use e steper motor or a servo. basicaly you need to build a turrent for the cammera so it can preform the nessasary movement. then you can use a gps module on the cammera and on the bracelet so that one is a master and the other is a slave, this the bracelet wil be the master and the slave will follow it, if its not over large distances say more than 200 - 400 meters then you can even use a bluetooth module instead of gps module, by using the bluetooth you will also set it up in a master/slave configuration and then program it as an 'iBeacon' function, this way the module will read the distance of the other module and electronicaly adjust position in the servo/motor to align the cammera with the bracelet. althou the bluetooth might be somewhat dificult, its much easier in setting up GPS tracking, you can look at setting up a fona feather with gps module or look at the simcom shield that has gps built into it. the GPS will alow for positioning and then the gprs can be set up for comunication, or once again if the distance is not to far you can use bluetooth for comunication.

Sorry, for some reason I just assumed you guys would be able to read my mind about this project hahaha.
To clarify, it will be a about 800m to 1200m away from the camera, which will be outdoors panning left to right no zoom no tilt or pitch, just panning in order to track the wristband on a flat desert open terrain.

Well that will be OK, at those distances position errors from the GPS (which are normal) will not have a significant affect..

I have designed system that receives GPS co-ordinates from a remote (and small) tracker transmitter via LoRa and uses a handheld receiver with its own GPS and display to give you a distance and direction between the two.

In lots of practical tests the accuracy is around 1 degree .........

The direction is true North, so you need to know the local magnetic declination to use a compass to know which direction to go searching.

Heres is almost exactly what I would like to create, but Ive got no idea how to start, the video is a bit vague

Start with the mechanics.

How do you build and setup a rig that can point the camera your going to usein one direction then another.

Good advice from srnet!

When you get around to the software, a similar project was disussed here here.  The sketch show how to calculate things for the camera, using my NeoGPS library; it's is smaller, faster and more accurate than all other libraries.  The example programs have the correct loop structure so you don't lose any data.  If nothing else, take a look at the Troubleshooting page for more tips on getting a GPS program to work reliably.
