Building Controller Boards and Interaction with Electronics
Its small size, low cost, and ease of programming make the
Raspberry Pi very useful in “embedded” applications. In these
types of project, the Pi is used along with other electronics
circuits to create everything from 3D printers, to home
automation systems and robots.
