25.1   Raspberry Pi and External Interface

 

25.1.1  Meaning of External Interface

 

Standard PCs like regular desktops can run the same program much faster than Raspberry Pi. However, Raspberry Pi has a capability that these standard PCs can not provide, which is a bidirectional interface with external devices. Raspberry Pi can communicate with and control devices outside the system through an interface with external devices. It can receive input or output through an external device, or control the external device. It is possible to receive a various measuring values ​​from an external sensor, to determine the situation, and to perform appropriate processing accordingly, or to build a system for directly controlling an external system by creating an embedded program.

 

Because Raspberry Pi is not only able to use resources within the system, but also has the ability to interface with various external devices, Raspberry Pi has conditions that can be used in almost all areas.
