LED-Wiz and LEDBlinky - Nothing lights up, need help.

OK.  I've been playing around with my LEDWiz and reading the directions again and realized I've been way overthinking things.   :o  I do that often.  LOL.  But in the picture you first posted just move the wire that you have in the ground terminal to the +5v terminal next to it.  Should work fine after that.

I would use a terminal strip similiar to this one.

You can hook up the +5v from the LEDWiz to it on one side and daisy chain it down that one side, then just hook the +5v lead from the LED's to the opposite side to supply it with 12 volts.  Will either need 3 of them for your 32 LED's or just put 3 LED's in each of the terminal strip ports.

Also 32 LED's will have you over 500mA if you are using the USB's power.  For single color LED's you are at 640mA (32LED's x 20mA).  If you are using all RGB LED's then you would be at 1920mA (32LED's x 60mA) as each LED is basically 3 LED's in one.

Took some pics that might help.
1st pic - Everything wired up.  All connected to the +5v off the LEDwiz.  Port 1 is Trackball Red, Port 2 is Trackball Green, Port 3 is Trackball Blue, and Ports 4,5,6,& 7 are single color blue LED's.

2nd pic - A closeup of the trackball RGB wires.  For clarification ?.  Not sure what I was thinking with this one.   :dunno

3rd pic - A closer view of the single color Blue LED's wires.

4th pic - Everything lit up and working.  I daisy chained the +5v from the LEDwiz to the LED's but since I don't have a terminal strip yet I just twisted the ends together and used a short wire with a clamp on the end to connect it to the LEDwiz.

I'll make a vid later today or tommorrow if you need one.

Ok, so, now I'm thinking of External power.

I have 3 LED-wiz's and, preferably, I'd like to have these all on 1 power supply. Is this possible?

If so, do I need a +15v power supply? (15 / 3 led-wiz = 5 each?) and what do I need to check to make sure that the mA is compatible?

P.S Thanks for your help! ... I've already picked up some terminal blocks its now just a matter of enough power.

Yes.  The same power supply can be used for all 3 LED-wiz's.

No.  Just use a +5v power supply.  Volts stay the same regardless of how many led-wizs you have hooked up.  You shouldn't have to worry about amperage too much if you're using an external source.

This is wonderful thanks!

I've decided I'm just going to wire it up to my computer power supply :) That seems like the most logical solution.

AlienInferno:

Awesome.  Did you finally get it to work?
