Chapter 4. Really Getting Started with Arduino

Now you’ll learn how to build and program an interactive device.

Anatomy of an Interactive Device

All of the objects we will build using Arduino follow a very simple pattern that we call the interactive device. The interactive device is an electronic circuit that is able to sense the environment by using sensors (electronic components that convert real-world measurements into electrical signals). The device processes the information it gets from the sensors with behaviour that’s described in the software. The device will then be able to interact with the world by using actuators, electronic components that can convert an electric signal into a physical action.
