I have a NeoPixel strip with 105 pixels...I'm testing the above circuit on my breadboard to power the strip before I get a PCB made for a much larger project (images attached are my schematic & pic of the breadboard w/ components).
Components pictured (left to right):
1N4001 - rectifier diode 100uF electrolytic capacitor LM7805 - 5 Volt regulator 10uF capacitor 1000uF capacitor (as suggested in the NeoPixel Uberguide)
(Not pictured - the wire I have going from the NeoPixel data line into pin #6 on my Arduino Uno)
I'm using a 5V 3000mA DC power adapter -- But no matter what 5V adapter I use, the strip just starts going crazy flashing at random, random variations of colors. Even when using the Adafruit example sketches w/ Arduino (strandtest, simple)
Can anyone figure out what I'm doing wrong here?
