LED Wiz wiring question
stephenp1983:
I am looking at getting the led-wiz + GP and approximately 6 of the nova gem buttons to be lighted. The buttons have two wires coming from them, so the one with the resistor would just be connected to the ledwiz in of the number terminals correct? Then the other wire would need to be daisy chained from each button into either the u5v terminal or the x5v terminal depending if I would be powering them via usb or an external power source correct?
So would a usb port provide enough power for just six of the nova gems, or would I Need another power source? Also on daisy chaining the wires from each button would I just twist them together and leave them, or what could I use to seal each twist between buttons.

Yes - USB will provide the power no problem. The easiest way to combine the wires (twisted together) would be with a small wire nut.

If I recall correctly, a USB port will provide up to 200ma of power to any source/s. Since the average draw from the LEDs (from GGG) used in NovaGem Buttons is 20ma, that would allow up to a max of 10 units per USB source. An external power source will offer more units per chain, dependant on the power source itself.

Could you provide a photo example?
