Alright, I'm trying to create I guess an LED matrix display(?) so that I can make essentially a text display using 8x5 LEDs per letter, to make 11 letters in total. I'm definitely willing to learn a lot and NEED to learn a lot as I have little experience with something like this. My goal is to be able to display individual letters to make the display show like "Hey there" using 5x8 LEDs for each letter.
I'm looking to use possibly an arduino device, but as they have limited inputs, and I need about 440 inputs.. how would I make this work? I've researched a bit and it seems I could do something related to this https://www.circuitspecialists.com/blog/build-8x8-led-matrix . Would this be my best bet maybe? How would I extend this from 64 to 440 in terms of delivering it to the arduino device?
Also I would like to ask what arduino device might be best for this, and what accessories I might need that aren't mentioned in that page, if the provided link is a good idea.
Edit: Sorry for being somewhat vague. I'd be using 5mm Red LEDs and I only need to be able to turn on and off each individual LED. https://www.circuitspecialists.com/bag-red5mm.html
