@mfalkvidd said in Incorrect lighting of ws2811b led strips. Wemos D1 Arduino controlled:
@Beeblebrox666 good work on isolating the problem.
There are led strips that light upp three and three. I have one myself (purchased by mistake)
It is also known that sellers on Ebay and Ali send different stuff for the same product. This happens from time to time.
So the simple explanation is that the seller sent you a different type of strip.
@mfalkvidd Thanks! This is the first project I had ever attempted with these components. It would be nice if the led strips themselves were printed with a code indicating type, Mine look identical to those my friend used with one exception, mine had wired plugs on both ends (One male, one female) If you have any info on how to use the 3 x 3 or whatever they are called, let me know... Again Thanks!
