Make a Neopixel Guggenhat! #AdafruitWeekendProject

Make a statement with this Adafruit Neopixel marquee hat tutorial

Adafruit’s Bluefruit devices are hands-down the easiest way to get Arduino communicating over a Bluetooth wireless connection. Bluetooth LE is a great way to control a project from a smartphone or tablet.

This simplicity could be illustrated with a scrolling LED wall sign that works with your phone or tablet…and it’s easy enough to link up a few 8×8 NeoPixel matrices.…but we’re a little more zany than that. And we’ve got a thing for wearable electronics. So…

A hat! A dapper top hat! Most exemplary! Rather than flat matrices, we’ll use flexible NeoPixel strip. To save a lot of cutting and soldering, let’s keep the whole strip intact and coil it around the hat. The project takes its name from the Solomon R. Guggenheim museum, with its landmark spiral gallery.

To make this project fun and easy to update, we use a Bluefruit LE module to allow text and color updates to be wirelessly controlled from any iOS (all iPhone/iPads) or Android 4.3+ device (check that your Android device has BLE as some older devices do not!)

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
