Arduino is an open source micro-controller.
A micro-controller is a programmable device that you can hook up all kinds of input devices (like sensors) and output devices (like motors and lights).
One way to hook up devices to Arduino is to use the Grove Base Shield (a *shield* is a card that you can plug into the Arduino to extend its capabilities.). You can then use lots of Grove Components with Arduino.
