I have reviewed this post with interest:
I am about to start the build of a 1:144 King George V, and looking for an Arduino solution for gun control. @ovalracer did you finally get this functioning?
You may get lucky with your request, let's hope so. However, unless the OP set up email alerts for his thread, he's unlikely to see your question. It's common for folks to come with a question and drop out of sight once it runs to a stop - solved or not, which is exactly what you'd expect, no criticism intended.
There have been several other similar threads - the forum is suggesting one about the Yamato to me for example. A servo based solution is common - you may want to use something like a Mega that can handle multiple servos or one of Adafruit's daisy-chainable boards that can do hundreds if required.
While we wait, perhaps you could post some pictures and indicate what you're looking to do with the ship's guns & turrets. Anything else to be controlled?.
It's also possible, given the OP's reachout for someone to help in person, that progress has been made outside of the forum. The only way we'd find out is if that helper 'fesses up' here on forum, which I suspect isn't very likely. Sad, but true.
Thanks for the comment and my fingers are crossed.
I have no images of the model as the key component is the gun control, if I can't get a solution then the build will not start.
I am hunting for a Arduino Gun control system that synchronises the 4 guns and gun aiming director. I wish also to add a compass board so that the guns remain on target as the ship turns.
I have seen a few Youtube videos where this has been done, but they are some years old
What you want to do sounds quite plausible, but don't expect that you'll find code online that does exactly what you want. You can find other folk's solutions and adapt them for your needs, though hacking them together will need a bit of coding knowledge.
I haven't seen one with the compass adjusting the train angle, though I expect someone somewhere has done it before. It sounds like a very worthwhile feature though and well within the capability of the Arduino.
You may want to follow the OPs example and find some programmer locally to work with - it will need many many debug cycles with the actual hardware to get it working I suspect.
Alternatively, you can get lots of help here as long as you're not expecting someone to write the whole thing for you although there is a section for paid help if you want to go that way.
Whereabouts are you?
Wildbill, Thanks again.
I am based in UK.
I am realistic and not expecting to get a code that completely fits my needs. But if one can get me almost there and some additional tweaking is done that would be awesome.
My coding is flakey but building on a good baseline I can usually get there.
It looks like you could use one of the versions of the Alabama code as a starting point. It has three turrets, which I believe is what you need.
IIRC, the problem observed there is jitter and many of the code versions have been tweaked to facilitate testing. It would give you a starting point, though I would be inclined to take enough to run the director and a single turret and build up from there.
Have you come across this: Wokwi? It would let you do online simulation of servos to test your code without the pesky hardware
