How can I build a relatively large scrolling LED display able to be outdoors and have programmable messages?
My dad has an interesting idea for his Chevy Blazer project car...he wants a scrolling LED matrix attached to the rear spoiler so that he can have messages shoot across it. Would it be moderately easy to make this or should I consider purchasing it? The display would be approximately 3-5" tall by 36" wide. I would need to know specs on the electronics (LED's, arduino, parts in general). Also, If it is best for me to purchase it, where should I look for the parts? Thanks.
