I'm completely new to the Arduino thing, so am just looking for a place to start in terms of researching how to do this project.
Basically I came across an old red LED display (Kind of like this - http://www.buy-led-signs.com/images/prodpics/indoor-red-965mm-scroller.jpg
). It connects to a box and its own keyboard via a parallel cable attached to the display. But these have been damaged.
Eventually I want to hook it up to a microphone so it can react to music. But until then I just want to get it working, e.g. being able to display words of my choice.
I don't want to have to link it up to a computer everytime I use it, as this affects portability. (For example, connecting the parallel cable to an Arduino and then usb stick with the programming to the same Arduino (if that's possible/ how it works))
Does anyone know what sort of things I should be looking at/ point me in the right direction. Any information would be helpful. Thanks.
