LED addressing?

Question

Microcontrollers

There is a warehouse with about 150 cells. It is required to automate the process of finding the desired cell. It happens like this: the storekeeper enters the number of the parcel (or something else) on the terminal -> the LED on the desired cell lights up. The software part doesn't really interest me. Need ideas on how to implement this in hardware. It is worth considering that the maximum length from the control device to the cell is 50 m. Any ideas?
PS system must be expandable

Answer 1

Any counter, the same K561IE in a cascade is the simplest and cheapest, the account can be set even through atiny with VUSB, even directly through LPT. The length of the cable and the power of the diodes are calculated locally, you may have to throw up the tranzyuks so that you can put normal light bulbs.

Answer 2

RS-485, any protocol that first throws the address of the device to the bus, which should listen to the next message on the bus.

Answer 3

Well, the only thing that comes to my mind is the implementation of the LED matrix. How to implement it comes to my mind at least 10 ways, and if you think about it, you can find 10 more.
If you really need it, order the development of a device (for example, from me) and don’t worry.
Distance is not a problem, data can be transmitted via RS-485, WiFi or radio

Answer 4

WS2811 individually addressable RGB LEDs - in my opinion there is nowhere easier to organize.
