Looking for LED help....
I'm looking for for help with a project I'm working on and I'm tryin g to build a *fairly* simple LED bar light (similar to that which you see on an F1 steering wheel or a car Tachometer) for a gaming wheel. Although I've done a lot of gooling and searched this forum I'm not sure where to start.
My aim is to have around 15 LEDs in a row (5 green, 5 red and 5 blue) that light up one by one (and remaining on) from the left to right. Its purely cosmetic and not conntected to anything. Ideally I'd want this to repeat 3 times on the when first powered then remain off until power is cut then restored.
Here's a link to something similar that I'm trying to achieve and picture embedded too
I'm sure this must be realtively simple to do but I'm lost where to start. Any help or simple to follow tutorials would be great.
