How would you light up sorting boxes in a warehouse?

Question

Arduino

Sorry for the non-obvious title and set of tags, but you can’t say otherwise)
So. Physical warehouse, sorting of small goods. The browser stack, that is, a person picks up the goods, scans the barcode in the browser application (on the web socket), the application shows which client to send the goods to. The person puts the goods in the right box. I want to replace these boxes with a large sorter - a structure consisting of cells of about 50 by 50 cm each. Each cell is a product of a specific client. And these cells should be highlighted depending on who the goods are intended for. Assemble the structure, for example, from water pipes (polyethylene? Plastic ones in general) - then you can put wires inside the tubes and bring diodes out.
I'm not an electronics engineer, not a circuit engineer, but very interesting)
Total question: how to light a light bulb on a certain physical cell at a certain event in the browser? What should be the soft and hard stack, what can and / or should be used? How to create a wiring, what components are needed?
Additional input: ideal - no wires between the sorter and the computer, because everything is fragile, and the warehouse guys are sharp and sloppy.
Let's say the lag is within a second or two, during which time a person manages to check that he really has the product that is displayed on the screen in his hands and switch the focus to where he puts this product.
There are many cells - 35 for example.
At first approximation, it seems that it could be like this: something is put on the sorter, with wi-fi on which you can raise a primitive http server, and a javascript handler with a conditional $.getScript is triggered in the browser, requesting this server in the local wi- fi network, and then something lights up the right light bulb. What could it be? How to assemble such a scheme? Or am I thinking in the wrong direction?

Answer 1

You wrote a very simple and working version. Any arduino + wifi-shield will do. Connect LEDs via shift register . Raise the web server, for example, like this .

Answer 2

Problem: there is no link "product<->cell" at the time of scanning.
Those. you need a person to scan the barcode once and it also contains the cell ID. Then everything is simple: a command is sent via a TCP socket to the desired block of cells and which cell to highlight with what color: CellID (
CellBlockID+Number), Color
terminals located on the bottom of the tray and on the reverse side of the bottom of the cells.
So that you can easily replace the required capacity of cell blocks (50x100, 100x100, 150x100, etc.).
In general, it is better to make electronic "trays" with illumination, and the bottom of the boxes - transparent.
