Without Internet? Answered

I'm looking to run a radio-controlled N-gauge model railway. An ESP-12 bareboard is small enough to fit in these tiny models and I would like them to be able to 'talk' to each other and to other line-side equipment is thia possible?

Short answer: probably. Longer answer: it depends. performance range will be impacted by the size of the space and the materials of the enclosure. Wifi may be one of the clunkier solutions for your project, as the devices don't naturally talk to each other directly, but rather talk to the network outside, then read info from the network to react. You might be better off with something like this: http://bluerailtrains.com/, but that might take some of the fun out, I dunno how "from scratch" you are looking to build. =]

Have you tried my beginner Arduino class? https://www.instructables.com/class/Arduino-Class/

Thanks Beka for such a rapid answer. You seemed to have, inadvertently, answered my question without realising it.

The heading of my question was 'Without Internet'. I have a large shed in which I intend to build my layout. I have already had grounded wire netting laid up behind the internal plaster-board in order to create a 'Faraday cage' {so no outside radio interference} which, of course, includes WiFi.

Thank you for the Bluerailtrains.com reference however they only work with HO gauge and above, N-Gauge is exactly half that HO.

Your suggestion. that they don't naturally talk to each other, answers my question. Thank you.
