That's about what are you talking about? :)
sure，if that is a bed solution or it can not help you , I'm very sorry about that.
I mean, can you show what exactly message are you responding on?
I'm replying this message , I used my phone before , I don't know how to reply it on the mobile site.But I think maybe you have aready used it on your solution.
Thanks for your help :)
But in real here is no problem about LED connection - there is no problem with it at all, because principally everything is connected and works. There was reflections on the topic about possibility of using serial connection for exchanging data with game about button presses and what exactly LEDs that need to be lit at some moment. Also, in case we are using optical switches - there is no way to connect LEDs like mechanical switch, also if you connect LED to mechanical switch - you cannot control LED from game itself, like it has to be. But your variant is easy to make and for those who do not need something like I want - it will work good :)
Also, I found another variant to work with. Raspberry Pi Pico can do same, it has two hardware UARTs, and program that doing this, it has USB functionality and gamepad program, also I'll try to make program to try plugin (it's finally ready) to work with arcade lighs. The main problem is to compile that everything into one program. And also problem is that Raspberry Pi Pico doesn't have 5v tolerant pins, so it needs to use level shifter to adapt levels from 5v devices to 3.3v that needed. For SHINSANWASWITCH it's pretty easy, I think, just to change one resistor (I hope so) with lower denomination that limits voltage to power the optocoupler's LED, so, maybe here pretty easy to do without level shifter. In other cases it will be needed, but I think only in case of using 5V UART device that will be LKP in my case. And if everything will be good, making a board for it will be pretty easy :)
I'll upload updates if I have news about it :)
I found something interesting about plexiglass, maybe if someone interested in making a slider that will scatter light the same way as the original slider on arcade cabinet can use it. I found that plexiglass is pretty good when sanding with sandpaper. I sanded down it with sandpaper from 60 to 800 (sandpaper grit level, from coarsest to finest) and I found it looks amazingly good and while maintaining sufficient transparency, so if you put a picture under it - it will look good, just like on real arcade and along with this, it’s all very pleasant to the touch due to processing with the finest sandpaper. So, I think I will use it in the future, when I'll have possibility to complete my build.
