To get started, let’s assume you have some model of Arduino microcontroller connected to the computer’s USB port. We’ll elaborate on the finer points of powering NeoPixels later, but for now you should use a separate 5V DC power supply (or a 3.7V lithium-ion battery for a Flora wearable project). | To get started, let’s assume you have some model of Arduino microcontroller connected to the computer’s USB port.
