​Arduino is a wildly popular hobby computing platform. Arduino refers to three things:

• A friendly software development environment that runs on Windows, Mac OS X, and Linux (get it ​here)
• A suite of single board computers (see ​here) based on AVR and ARM processors
• A standard stackable ​interface that lets you plug "shields" into the single-board computers to extend their functionality with things like ​motor control, ​Ethernet, ​WiFi, etc.

We use Arduino computers on Team 2537 because they are very inexpensive (often available for less than $4) and are designed to connect to the real world. Arduino computers can easily be connected to sensors that provide information about the real world and actuators such as motors and solenoids that can interact with the world.

Team 2537 has a set of lessons that introduce you to Arduino through hands-on projects culminating in mini-robots that you design.
