# Adafruit QT Py and NeoPixel LEDs

## Overview

![](https://cdn-learn.adafruit.com/assets/assets/000/095/825/medium800/leds_QT_Py_basic_animations.png?1602693460)

The QT Py is a tiny little development board capable of big things. Big things are great, but LEDs are the best. QT Py plus LEDs is even better! This guide will help you get started using NeoPixel LEDs with your QT Py and QT Py Haxpress (A QT Py with a soldered-on flash chip). You'll learn how to wire up the board and LEDs, and how to get the software set up.

For the QT Py, you'll be provided with an example that includes some simple animations, such as blink and chase, with basic customisations so you can modify them to fit your needs.

If you've soldered up a QT Py Haxpress, you have the option to use it with the CircuitPython LED Animation library. This guide includes a page on how to use the LED Animation library with your QT Py Haxpress, with three examples to get you started, as well as links to details and more animations.

Let's get blinking!
