Now, the idea is to present an effect that suits well for the use of moders. A 10 LED runner. A connection that enables a row of 10 LEDs to light up in a wanted sequence. Resembles much of the Night Rider’s lights, but running only in one way. Exeptionally, we don’t introduce a premade mod, so in the first part of the article we’ll tell about the theory and an example connection. We have the complete mod in the next part.
