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 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 implemented as software. The device will then be able to interact with the world using actuators, electronic components that can convert an electric signal into a physical action.
