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!).
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
