Actuators: these components manipulate the Environment, themselves, or the area around them.Boards: microcontrollers (MCU-PT), single boarded computers (SBC-PT), and a special device called Thing which are used to create self-contained physical objects like coffee makers or smoke alarms.There are three subcategories for Components : These are simple devices that only communicate through their analog or digital slots. They typically does not have a network interface and rely on the MCU-PT or SBC-PT for network access. Components are physical objects that connect to microcontroller (MCU-PT) or single boarded computers (SBC-PT).
They are separated into 4 subcategories : Home, Smart City, Industrial, and Power Grid. In addition to classical network devices such as routers and switches available in the previous versions, Packet Tracer 8.0 Components Box now contains a wide variety of Smart Things and components : Things and Components available in Packet Tracer 8.0
