Hector’s MIDI NeoPixel Necktie #WearableWednesday

Hector wrote in to share his MIDI necktie with FLORA NeoPixels, controlled by Pinoccio, Abelton, and Max/MSP.

Internet connected wearable devices are getting more and more common these days. There are many devices available off-the-shelf right now, but there is something special about being able to imagine and create your own. To accomplish this, I truly think the best platform right now is to use a Pinoccio.

Pinoccio is a tiny little Arduino compatible board with Internet and connectivity built right into its DNA. I recently picked a kit up and I’ve been impressed by its ease of use. If you have Arduino experience, you can most definitely program a Pinoccio. It even has a scripting language (bitlash) baked right in, so only if you really need to, you need to go to the Arduino IDE. Moreover, the guys at Pinoccio provide a pretty intuitive web-interface and a Rest API to access your boards remotely from anywhere with Internet access.

The next ingredient on this specific recipe is a handful of Adafruit’s awesome Flora NeoPixels. NeoPixels are chainable, individually addressable RGB LED’s with a built-in current driver. Conveniently, the NeoPixel chain only uses 1 digital pin on the Pinoccio, leaving a lot of free room for interacting with other sensors or devices on your project.

To drive the NeoPixel chain with the Pinoccio, I wrote a library that extends the Pinoccio scripting language environment with functions to interact with the pixels right from the web or the API. I’ve made the library available.
