I've searched for the past couple of days how to achieve this, but I'm not experienced enough to know how to even ask the question to find related answers. Hopefully, someone here can point me in the right direction.
What I want to do is setup a server that is hosting a web page - local only, not on the internet.
On that webpage I want to display a slide show. Either pictures with text or just an array with actual text.
What I'm wanting to do is advance these picture or array elements via external control.
For example, if I want "slide 37" or "array element 37" displayed in the page I'd like to click a button on a DIFFERENT computer on the same network and have the server update it's webpage.
I'm assuming I'll need to utilize websocket in order for clients to see those updates in realtime, but I'm not to that point yet. I'm trying to figure out the external control first.
I apologize for my lack of vocabulary in regards to what I'm trying to do. But that's why I'm here - trying to learn :)
Thanks for the help!
