Arduino Mini Pro not working with my Neopixel project
As I was playing around today I found a solution. Powering the board through the FTDI adapter, which in turn was being powered by a USB juicepack charger, wasn't supplying enough juice and/or ground. It was enough for the Uno to work, so that's what was confusing me. I soldered in a 9V battery and clamped down on the pins with a wrench to ground it out. That made the board happy and it kicked into gear and lit my project up perfectly. It's pretty ghetto but it works! Yeah! :D
