A PIC is used as a SPI Master to create a simple interface to up to 21845 NeoPixels. After being configured with the number of attached NeoPixels the Pixif continuously retrieves the RGB values via SPI and generates the NeoPixel GRB bitstream. The update rate may be throttled via a synchronization input. This approach frees the host processor to concentrate on its algorithms especially when its SPI Slave has DMA support.
Resistance is futile! The Borg are among Star Trek's most iconic and terrifying villains. Whether its for Halloween or your next Sci-Fi con, this guide will show how can easily put together a great looking Borg costume. By assimilating and adapting some other projects on the site it can really stand out.
If you're like me, you loved the Adafruit Daft Punk helmet that showed up on our blog a few weeks ago... but, as my 3D printer is a little bit smaller than a TAZ, and funds and time are limited, I thought for Halloween I would make my own version, based around a $5 mask from Party City that looks a little bit like Cobra Commander.
Adafruit's Bluefruit HID controller is the easiest way to instantly add an HID keyboard or mouse interface to your project, even without a microcontroller. Did you know that you can also use it to convert a normal wired keyboard to supporting Bluetooth? In this project you'll learn exactly how to do it.. and in the process you'll bring an iconic piece of computing hardware into the modern age. Time to start digging around in your closet for that old IBM PC you haven't seen for a few years, because with Bluefruit and the Model M, "it just clicks".
In this project, we are going to interface a USB camera to an Arduino Yun to make exciting applications. The first one is to take a picture & upload it automatically to Dropbox when motion is detected. We'll also make the camera stream video wirelessly to Youtube, so you can monitor your home from anywhere!
