Arduino is a cheap microcontroller, a bit like a computer, that you can program to do things. You can attach a whole range of sensors, motors, lights, and speakers to create robots, automated pet feeders or a plant watering system. You can also use Arduino to control any modern household device.
We speak to one of arduino's inventors, Massimo Banzi, and also to Mayur Panchal and Baxter and Kahu Kirikiri who are doing some cool things with it.
