Mechatronics 1: Week 7 - Sensors and Actuators

Sensors and Actuators: The Bridge to the Physical World

This week, we explore the crucial components that allow mechatronic systems to interact with the physical world: sensors for gathering information and actuators for taking action. Understanding these elements is vital for designing intelligent and responsive systems.

Interactive Sandbox: Smart Lighting System

This simulation demonstrates a basic smart lighting system. Adjust the 'Ambient Light' slider (simulating a photoresistor/LDR) to see how the LED brightness changes and how a simulated DC motor (e.g., for blinds) responds based on programmed logic.

Input: Ambient Light Sensor

Ambient Light Level: Value: 500 (Medium)

Pseudo-Code:

Outputs: LED & Motor

LED Brightness

Brightness: 50%

DC Motor (for Blinds)

Stopped
