Pixy, CMUcam5 Smart Vision Sensor Camera

Pixy CMUcam5 Image Sensor is a fast vision sensor you can quickly "teach" to find objects. It connects directly to Arduino and other controllers. Pixy pairs a powerful dedicated processor and image sensor. Pixy processes images from the image sensor and only sends the useful information (e.g. purple dinosaur detected at x=54, y=103) to your microcontroller. The information is available through one of several interfaces: UART serial, SPI, I2C, USB, or digital/analog output so your Arduino or other microcontroller can talk easily with Pixy and still have plenty of CPU available for other tasks.
