Hi,
I have a oontz assembled that's not working. I've checked all pad. Every Pad has the same following values :
Vin : 5v
SCL : 3.37v
SDA: 5v
I tested every led before soldering. I first board alone was working. I double checked the address for each board and they should be fine.
I tried the Onntz code provided on the tutorial, the one for Trellis and all examples (test, game of life...)
Any idea fo this?
Thank you for your help

Re: OOntz not working
Could you post clear pictures of your board and the connections to it?

Re: OOntz not working
It kinda looks like you used red wire to connect to ground, and black wire to connect to 5V. Make sure your wire colors connect to the right pins, since our diagrams use color to help match. please fix the wire colors and show how you are connected to the Arduino once that's fixed

Re: OOntz not working
obviously on the arduino side, The colors are inverted too. I just didn't want to twist the wires.

Re: OOntz not working
sometimes its obvious sometimes it isn't :) please fix the wire colors up so they match up right and let us know what does work and what does - do any LEDs light? does the sketch upload right? you said you tested the first board, what about the others?
