So I ordered 5 of the Neopixel 'Jewels'.. they arrived..
I wired them all up in series.... (cap and resistor as well)... when I uploaded the code, and powered things up..
only the first '2' Jewels (each Jewel consists of 7 leds each, just so we are all on the same page here!) :) lit up!
The remaining '3' jewels did nothing..
I un-soldered the Jewels/pcbs' that were working.. and tried them each individually on the Arduino Nano...
but again.. the first '2' pcb's (Jewels) are working fine still...... I'm guess bad luck and I got some duds? (which is a bit odd)..
So my question(s) to you all are:
1.) Is there any know mfg. glitch/change that is known out there? Such as: "oh I read that in some clones these pads are reversed..etc" (or whatever)
2.) I'm not clear on the exact pin-out/schematic on these Jewels... I wanted to check if these were perhaps used before? and the first led was blown? (but I'm not clear on the pinout of the 5050 package, and what order the next led is, to try and jumper the DATA IN to the next led? see if its just the first led blown.. and perhaps I can replace it?)
3.) Anyone know of a FAST USA located seller/store where I can buy some new ones from? (cheap?)... its for a Halloween costume that needs to get shipped out by (I think) the 17th of this month to make it in time!
Appreciate all suggestions!
