Hi, I'm kinda new to electronics, I know some basic things and I'm trying to create a scrolling led light bar for a project, the led bar is around half inch by 4 inches long, I want the led to scroll from left to right or right to left like the text ones but no text (not sure what the correct term is). I can manage this with an arduino but I don't have space for it in this project, is there another way to create the circuit board as small as possible? Thanks
