Dotstar LED strip extra + and - wires

by jackieh111 on Thu Jun 08, 2017 3:34 pm

I'm feeling very dump but can't find an answer to this - what should I do with the extra + and - wires on the Dotstar led strip ?

Thanks for your help.

Can you elaborate on what you mean by 'extra'?

Hi,

The wires on the DotStar have 4 wires (ground, power, clock and data) plus two extra wires red and black - I'm assuming they are ground and power too. I can't see in any of the tutorials what I should do with these. For example, I'm doing the bike POV tutorial - there is no reference to these wires - should I cut them off or solder them to the other power and ground wires.

Thanks fro your help.

Can you post a photo showing these wires coming out of the Dotstar strip.

At both ends you will see the extra wires I'm talking about - I don't know what to do with them.

Pretty sure those are going to be just extra GND and POWER leads. See this thread:
viewtopic.php?f=47&t=70990

But also best to try and verify this yourself. You can visually check the labels on the strip to figure out what wire does what. See here:

And you could do a continuity check on the two red leads and the two black leads to see if they are common.
