The Intel Galileo
The Intel Galileo is a small programmable computer that we can use to make all kinds of clever interactive gadgets and gizmos. It is not a computer like the laptops we have on our desks, because rather than having only one set of inputs and outputs (the keyboard and mouse, and the monitor), it has literally dozens, all of which we can program to read and control all manner of electrical gadgets.
The Galileo is based on the popular Arduino microcomputer platfrom, and is completely compatible with the Arduino UNO. However, it packs a load of extra features, such as in-built networking, wifi, usb, and a full linux-based operating system. These extra features allow us to connect to and program the galileo as if it were a regular computer.
Today we're going to be exploring the many different ways we can interact with the Galileo, using physical interfaces such as knobs, buttons and light-detectors, and virtually wiring them to outputs using the web-based Connect Anything interface.
You can access the Connect Anything interface by connecting to the Galileo's wifi (it acts as an access point), and going to cat.com (if you're not connected to the Galileo's wifi, all you'll see is the website for Caterpillar!). It allows you to route any of the inputs of the Galileo to any of its outputs using a simple touch interface!
The links below give you a run-down of the inputs and outputs connected to the Galileos in front of you. Have a read and a play, and let's make some sound, light and motion!

Inputs
The galileo can receive and send many different types of signal on many of its different pins. The pins we’re going to be using today to receive signals are shown below: These pins can recieve voltages between 0 and 5 Volts: If you attach a device that outputs any voltage...

Outputs
The outputs of the galileo are shown in the diagram below: The galileo can output two types of signal: Digital on/off signals, and Analog continuous signals (labelled PWM) - think of it like the difference between a regular light-switch and a dimmer switch. The board can output digital signals on...
