I've got a 9V battery and I want to power my Arduino Nano clone (SainSmart Nano 3) and some Neopixel like LEDs. So I uploaded a simple animation to my Arduino via USB and exevrything is working fine.
When I disconnect USB, and connect the 9V battery, it runs the sketch, but stops at the sane point every time I tried it :( And the LEDs are also not bright white with the battery, but orange!?

Does anyone has an idea, why this is happening?
