Hi there, So I am essentially creating a long string of RGB LED's using Adafruit's NEO Pixel strip (I am cutting them at each intersection and rewiring to extend the length between each) with a total of 111 LEDs. My plan was obviously to power the LEDs (wired up to the arduino) with an external 5v/…

You shouldn't plug 5V into the arduino ext pwr jack. The alllowAble input voltage range for that ja k is 7 to 12V dc.
What is the total current needed to power all 111 leds?
