Electronic systems Flashcards
What is a microcontroller?
A small computer on a single chip that controls devices. It stores programs, processes inputs, and controls outputs
What are the main components of an electronic system?
Input devices
Processing unit
Output devices
Power supply
What are system inputs in an electronic system?
Inputs are devices or sensors that detect changes in the environment or the system
What are system outputs in an electronic system?
Outputs are devices that display the result or action after the processing of inputs
What is the purpose of a microcontroller in an electronic system?
A microcontroller processes input signals, executes a program, and controls output devices.
What are the advantages of using microcontrollers?
Reprogrammable and customizable
Small, compact, and cost-effective
Low power consumption
Can control multiple devices
What is the Internet of Things (IoT)?
The IoT is a network of physical devices connected to the internet that can collect and exchange data
What are the advantages of the IoT?
Remote monitoring and control
Automation and energy efficiency
Data-driven decision-making (e.g. tracking health, smart home control)
What are the disadvantages of the IoT?
Privacy and security concerns (hacking risks)
Dependence on internet access
High setup and maintenance costs
What is a sensor in an electronic system?
A device that detects physical changes and converts them into an electrical signal to be processed by a system
What is an actuator in an electronic system?
A device that performs an action or movement based on signals received from the system, such as turning on a motor, moving a robot arm, or opening a valve
What are the inputs, process, and outputs in a simple electronic system?
Input: A sensor detects a change
Process: The microcontroller processes the input
Output: The system activates an output device
