Quick question on project feasibility from a total arduino noob

Projects General Guidance
1

I've got a project that I need to see if an Arduino system would work, basically I've got to convert 32 line by line (decimal) inputs into a binary output. I can change the voltage of the inputs to meet the Arduino specifications but I need advice to see if it can be done (programming wise) and which Arduino system would be best for my solution.

Thanks for your time.

Please explain further what you mean by "32 line by line (decimal) inputs".

32 numbered wires, analog input, when a wire turns on I need to convert the number wire to a 5 wire binary output (output wires will simulate a binary logic).

It's for an elevator system, old school used to have a single wire representing a floor, it went high and a light would turn on, 80-90's came along and it went binary which I can convert to more modern communication methods, I can convert upto 16 line per floor inputs with current products but this job requires more and I'm looking at different methods to convert more inputs into a binary output.

Ok, so you need a couple of analog switches connected to 2 analog input pins

You go thru and sample each one, when one becomes active you send out its address.
Or, if you can treat them as digital signals, running each thru a resistor divider if needed to stay within 0-5V levels, then you can sample them all with a set of 4 74HC165 parallel to serial shift-in registers, and send out the 5-bit address of the input bit that changed. Use SPI.transfer() or shiftIn() to read 4 bytes from the daisy chained parts.

links didn't work.....

So it is possible, that's great, another stupid question which Arduino processor? I assume just the basic uno since it's not that complicated of a setup.

Copy & paste them in, forum seems to be adding extra characters to the front of them.
Uno will do. USB output? TTL level Serial? RS485? Promini with an appropriate adapter might do.

Dunno just yet, looking into different avenues currently, thanks for the advice.
