Description

LED (Light Emitting Diode) A LED is a semiconductor device that emits visible light when an electric current flows through it. LEDs are widely used in indicators, display panels, and energy-efficient lighting solutions due to their low power consumption and long lifespan. Features: Operating Voltage: 1.8V - 3.3V (varies by color) Power Efficiency: High (compared to incandescent bulbs) Colors Available: Red, Green, Blue, White, RGB, etc. Lifespan: Up to 50,000 hours Applications: Status indicators in electronic devices Display panels and advertisement boards LED backlighting in TVs and monitors Smart lighting solutions (e.g., RGB LED strips)

Output Device

An Output Device is any electronic component that displays, signals, or transmits processed information from a system. These are commonly used in computers, embedded systems, and automation. Types of Output Devices: Displays (LCD, OLED, LED Screens) – Visual output Speakers & Buzzers – Audio output Motors (Servo, Stepper, DC Motors) – Motion output Relays & Actuators – Switching high-power devices Applications: Digital displays in consumer electronics Notification systems using LEDs and buzzers Motor control in robotics and industrial automation
