Neopixel digital rgb led strip doesn't work
I have a 1000μF capacitor connecting the power and the ground, and a 470Ω resistor on the data input.
I have checked that the datastream is connected to the correct side of the strip.
I have tried multiple ports on the arduino, as well as trying a basic code that I wrote myself to see if the strandtest sample code was the issue.

What power supply are you running? It sounds like a software error, but it doesn't hurt to check the voltage from the supply to the breadboard and the breadboard to the strip.

You need a ground between the Mega and the strand. Take a look at the NeoPixel Uber Guide
