hey guys, i am struggling with this all day long.
I don't have a UNO board, so i am trying to use a mega as main board and a pro mini as backpack.
i installed the node_pixel_firmata in the mega board, connected the sda and scl pins in the pro mini board and uploaded the backpack firmware.
i connected the strip in the pin 6 on the backpack board but not seems to work! :(
what could be the problem?
i tested all examples and the codes of the readme session, but it's all the same:
1529526591074 Available /dev/cu.usbmodem3131
1529526591098 Connected /dev/cu.usbmodem3131
1529526594305 Repl Initialized
Board ready, lets add light
Strip ready, let's go
no errors but no lights either
