What is an Arduino and why should you care? Arduinos are a family of inexpensive, easy to use microcontrollers that are changing the world by making complex computer controlled devices easier to build. They can operate a quadcopter or a 3d printer, or a robot or water your garden. Stop by to learn a little about Arduinos and some of the other microcontroller development platforms and how you can use them in your own projects. Bring your microcontroller projects and a question or two. If there is enough interest we might make this a regular event.
