Hi boys. I am looking for a person able to help me with the creation of a graphical interface for a car wash with coin like the one in the example below
Also, if you can tell me how you see such a project from your point of view and what components I need to make this project.
In the event that someone is interested in carrying out this project at a cost I expect offers and opinions. Thank you

You do realise that these terminals do not have a coin acceptor? Anyway, if you want to bring it to live you'll need ~ 10k. If you are interested, drop me a PM.

I've merged your cross posts @car-wash.
Cross posting is against the rules of the forum. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend 15 minutes writing a detailed answer on this thread, without knowing that someone else already did the same in the other thread.
Repeated cross posting will result in a suspension from the forum.
In the future, please take some time to pick the forum section that best suits the topic of your question and then only post once to that forum section. This is basic forum etiquette, as explained in the sticky "How to use this forum - please read." post you will find at the top of every forum section. It contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.

Thanks for understanding and for associating your two posts with me. By accident I posted in a wrong category and then I found this category in the forum.

Thanks for the reply. This payment terminal will also have a coin acceptor. In fact I have the payment terminals and they have integrated coin acceptor and the other components. Currently the installation works with a mini display connected with 4 wires. To these 4 wires I want to add Arduino and Matrix led rgb. The car wash installation has 4 washing programs "1- pressure wash, 2- foam, 3 - rinse with softened water, 4 - stop" I think I can connect instead of the existing buttons touch screen buttons.
10k seems like a huge sum to me for this project. The project does not have to be built from scratch and all the settings, programming for coin acceptor, electronic board for time ... all already exist. Like I said I just want to connect metrix led rgb to the 4 existing wires that currently work with a mini display.
Now if you compare the information you gave in #6 with the information in #1 then you might see a slight difference: #1: build from scratch, no plan. #5: almost all done, just some tiny bits to do. Maybe you could post what you have (datasheets, schematics, photos ...), otherwise it's guesswork (and that increases the price)
I am sorry but I cannot add pictures, I have tried repeatedly but I cannot ...
You'll need some documentation from the protocol said display "speaks" or at least a closeup of the backside of the display so one can read the chips/pcb text and/or markings.
And what do you wangt to do now exactly? add a multicolored LED to the display?

I want to create a plexiglas overlay interface that contains 4 buttons. On the back of the overlay in the button frames I want to paste the touch screen switch that I will connect instead of the existing buttons. Also behind this overlay I want to paste matrix led rgb with the arduino module to take over the countdown timer functions and display the program chosen by the client.
I will try to undo the electronic display and take some pictures may be helpful to see if the Arduino module can be connected as a replacement to that existing display.
I do not have documents with the operation mode of this display. The company that made this installation does not provide information on the functioning and manufacture of the components. They sell the complete modules
It'd be easier to remove the old stuff, keep the coin acceptor and rebuild the rest. The gray blocks with lots of cables, are these the relays? IMO the control unit is nowhere to see. Check what powersupply you have built in, the datasheet of the relays (at least photos of the markings), what coin acceptor you have.

The whole installation is a whole and it is quite complicated as far as I can imagine. The installation has a main electronic board after a secondary one that I think is a timer controller to which the buttons and the Alberici acceptor coin are connected. From the motherboard, the LED display is connected, which has no connection with the timer controller board. The motherboard has the possibility to connect a keyboard for managing and modifying the operating parameters. I think it is best to connect matrix led rgb as a replacement to the existing display.
Then you'll need the datasheet of the display.
I agree with zweiblum on this.
That doesn’t mean replacing the ‘main’ controller, but replacing the whole user panel. The existing panels appear to be pretty simple. Coin acceptor, LCD and four illuminated buttons. Plus several valves and pump relays for each wash bay.
But you need to know & understand the simple signalling from the controller to the panel and actuators. You also need to specify what’s displayed on the touchscreen display.
That being said, there would be many advantages to replacing the ‘whole’ system for flexibility and expandability. This could be as simple as multiple Nanos, and a smarter host (Due) etc.
Best case, you could probably use a single controller to operate multiple wash bays. Then consider newer features like contactless payments etc.
Thanks for the answers. Today I disassembled that display to take some pictures to see what it is about in that display. I would like to mention that it consists of 2 electronic plates to which the 4 electrical wires are connected. I know that it is much better if I redo the entire payment system only because here are some problems: 1 - compatibility because this installation works with written microprocessors and I think they are protected by copyright and I do not know if it is possible to access what is transcribed on these microprocessors.
2 - I did not find the person who can make these changes and who can give me the best solutions.
3 - The installation works very well and without problems and for this reason I do not want to enter too much inside it, I just want to see if it is possible to connect arduino and matrix led instead of the existing display.
This display displays with the coin countdown timer function or the token inserted in the coin acceptor.
The manufacturer of this car wash installation preferred not to use PLCs for the automation of the installation, using electronic books with microprocessors written by them and for which I have no technical documentation and do not want to make them available to consumers. This project can only be realized if we manage to connect the arduino to the 4 wires that connect the display.

Could you please post hires phostos of the display PCP (the red PCB), so that I can read the morkings on the chips and the vias? And one where the writing on the white lable on the display is readable?
Note: the LCD is fairly standard. In theory you could get away with a display emulator that's connected to the wires of the display (where the red PCD and display meet).
Note 2: White lable on display: Might be it says "KS0066U". Could you please check?
If I was commissioning such a project of "freshening up" the user interface to this car wash, I'd also consider a least invasive solution. The OP has already spoken of putting a plexiglass, some touch sensitive buttons behind it and a new display. For one thing, if something goes wrong, even if not related to the new electronics, there is always the fall back solution of putting the car wash back to its original state and trying to find a technician familiar with car washes to repair it.
Capacitive buttons can operate even behind quite thick plexiglass.
One relay per button (e.g. Lavage) can simulate a user directly pressing the button.
That leaves "only" the problem of the existing display module.
There are 4 connections to it. I could guess for power and a basic serial protocol something like RS485. What has to be seen is how heavily encoded it is. That is whether it more or less 1:1 takes what is sent to it from the master and displays it on the screen, or whether there is a decoding table built in to it of the form: 01="Bonjour" ; 02="Commence" etc. I'd guess that because there may be several of these display modules in car wash installation, it would be the 1:1 model because it could handle changes like the introduction of new wash cycles and their corresponding dialogues more easily, without individual software updates, and also would not be specific to a particular installation.
For the OP:
