Make a Map Game Tablet

Using Arduino Project Guidance
1

I want to make an arduino based electronic map game 10' tablet for my kids, I'll be using an SSD1306 OLED display for HUD. But the map itself will have many countries according to the continent, each country will have a led for indication, but I don't know how to add touch sensing to all 50+ countries. Please help, what material to use? At first I wanted to use a touchscreen display, but I'm trying to reduce costs at all cost... the only solution I came up with, is to use a pen that will complete the circuit, but I want to use it as a last resort.

Thanks in advance.

The SSD1306 OLED display is tiny. I am not clear what it will be used for in the project.

If you want to sense a touch at one of 50+ places on a display then it either needs to support the return of X/Y coordinates so that you can identify where it was touched or you provide an explicit switch for each are and sense that one has been operated.

More details of your proposed map would be helpful. Is it really 10' (10 feet) in size ?

I meant to say 10'' inches, I'm not a native english speaker, sorry.

well, the OLED display will be used for game options and points.
But the map, is going to have some countries, that have LEDs to indicate their position. As the game will be running, the name of the country will be displayed on the screen and the LED of the corresponding country will turn ON.

Now, I don't know how I will make it possible for each country to have a touch sensor or human finger continuity or something for the kids to interact with the unique countries.

thanks

No problem. I didn't really think that it would be 10 feet in size :slight_smile:

As to the inputs, 50+ switches in 10 inches square is doing to be a challenge, to say nothing of connecting them to the Arduino

Could each country be given a number that could be entered by the users to select a country ?

Well, I was thinking of adding a cartesian touch system on the map instead of having all 50+ individually sensed.

but I don't know how to do it. I don't even know how to search for it.

Good luck with that. I do not know how commercially available touch screens sense the touch but I am sure that it won't be easy to replicate.

As each country on the map will have it's own LED there will already be a good deal of wiring in place although using NeoPixel LEDs or equivalent would reduce that to a minimum

Have you considered doing the whole thing on an Android tablet and not using an Arduino at all ?

Not all English speakers use feet and inches! Many use metres, like the rest of the world does.

What will the board be made of? Wood/plywood/MDF?

What about conductive paint? You could paint the shapes of the countries, being careful to leave gaps between them. Holes drilled through the board could carry wires contacting the paint and leading back to capacitive touch sensors.

The conductive paint and capacitive sensors would probably cost more than a used android tablet.

I've had some thinking time and I have made a consideration to use android tablets instead... thanks everyone
