I am going to be controlling a large amount of neopixel buttons (maybe 100). The Arduino cannot power that many LEDs and the whole project should be powered by a single 9v wire leading to the wall. I cannot use the Arduino breadboard modules as they are rated at 700mA and each LED can use upto 60ma.…
