Anyone know the name of this displays?
Where can I find something like this?
Is it possible to control this with arduino?
So, basically, with right components, I should be able to use "one arduino" to control 10pcs of 5digit seperate 7segment led groups?
Can someone look at that tutorial http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Components/General%20IC/arduino_segment_led.zip and maybe simplify it for us newbies?
You should be able to do it using only three pins, plus power/ground with the right driver chip! So no need for I/O expanders unless you really want them.

Only works with common cathode displays though, so if you have common anode you'd need something else... but it was pretty easy to get running and I'm hardly an expert user!
I also want to be able to control those 5 digit leds dynamically with a data feed coming to the arduino board from a computer (for example : led no 3 = 25345 or led no 1 = 00293) so that's another weird part.
