Adafruit Industries is an open-source hardware company based in New York City. It was founded by Limor Fried in 2005. The company designs, manufactures and sells a number of electronics products, electronics components, tools and accessories. It also produces a number of learning resources, including live and recorded videos related to electronics, technology, and programming. History Limor Fried, then a student at Massachusetts Institute of Technology, began selling electronic kits on her website from her own designs in 2005. She later moved to New York City and established Adafruit Industries. In 2010, Adafruit offered a reward for whoever could hack Microsoft's Kinect to make its motion sensing capabilities available for use for other projects. This reward was increased to $2,000 and then $3,000 following Microsoft's concerns about tampering. The company had $22 million in revenue in 2013 and $33 million in 2014. Company name The name Adafruit comes from Fried's online moniker "Ladyada", itself a homage to computer science pioneer Ada Lovelace. The company's goal is to get more people involved in technology, science and engineering. Products In addition to distributing third-party components and boards such as the Raspberry Pi, Adafruit develops and sells its own development boards for educational and hobbyist purposes. In 2016, the company released the Circuit Playground, a board with an Atmel ATmega32u4 microcontroller and a variety of sensors, followed in 2017 by the more powerful Atmel SAMD21 based Circuit Playground Express. They, like many Adafruit products, are circular in shape for ease of use in education and wearable electronics projects, along with the FLORA and Gemma, the company's wearable electronics development platforms. In 2017, Adafruit Industries best selling product was the Circuit Playground Express NeoPixel NeoPixel is Adafruit's brand of individually addressable red-green-blue (RGB) LED. They are based on the WS2812 LED and WS2811 driver, where the WS2811 is integrated into the LED, for reduced footprint. Adafruit manufactures several products with NeoPixels with form factors such as strips, rings, matrices, Arduino shields, traditional five-millimeter cylinder LED and individual NeoPixel with or without a PCB. The control protocol for NeoPixels is based on only one communication wire. Adafruit provides an Arduino library and a Python Library to help with the programming of NeoPixels. In addition to the traditional RGB technology, Adafruit manufactures a red-green-blue-white (RGBW) variant of NeoPixel for all products except those that feature a NeoPixel Mini 3535. Those integrate an additional white LED in
