We can use that to modify each LED in a sequence – or every other LED, or whatever you like. How does it work? We're gonna use another for loop !Īs we saw before, for loops are useful for nudging a number higher. This guy will light up your LEDs green, one at a time. Let's take a look!įile > Examples > Adafruit NeoPixel > simple Once it's up again, you'll have some new example sketches. If you don't have one yet, go ahead and create it.) Also, restart the Arduino IDE if you already had it open. (The "libraries" folder is usually created in the same "Arduino" folder where you save your sketches.

You can just download the.zip file with the library, unzip it on your computer, and drag the contents into your Arduino libraries folder.
Go download Adafruit's NeoPixel library to get started. Pay attention to the labels, as well as the schematic :) Note: Depending on where you buy your "NeoPixels", you may end up with something that has the pins in a different arrangement. (It helps to chant this in your head, if you're doing lots of them.) The arrows should point away from your headers. Solder some male-male headers to the end, with the little arrows on the LED strip pointing away. That leaves you with solderable pads on each end, which will allow you to chain them together after the fact. You can cut the strips to any length you like to do so, make sure you cut across the center of the oblong copper pads. For this tutorial, we'll assume that you're working with LED strips – the simplest way to light up your bike, bar, CPU tower, and so forth.
