- If you want to get really crazy, hackaday demonstrates how to power 1000 NeoPixels with the Arduino's limited RAM.
- Why not bring your visualizer along with you to a music venue? Mark Easley over at hackster shows us how to integrate some LEDs into your clothes.
- Of course, if you are going to wear it, you may want to consider some portable sources of power. Check out the Sunny Buddy Hookup Guide to learn how to efficiently charge a battery with solar power.
- Or check out the Mean Well LED Switching Power Supply Hookup Guide when daisy chaining LED strips.

AzureWave Thing Plus (AW-CU488) Hookup Guide
The SparkFun AzureWave Thing Plus is a Feather form-factor development board equipped with the AW-CU488. We'll highlight key features of the board and show you to get started with the development board. A few Arduino examples will be highlighted to connect to a WiFi router, calculate the Fast Fourier Transform (FFT) from an input microphone, output an analog signal to a speaker, and connect an Qwiic-enabled device.
