SMART SYSTEMS 3

This lecture provides information on various electronic components and their functions. It explains the difference between voltage and current and the importance of resistance in limiting current flow. The text emphasizes the need for caution when handling electronic components, including avoiding short circuits and checking input and output devices for acceptable voltage ranges and current draw.

 

The  use of transducers to convert one form of energy to another and their application as inputs and outputs in circuits. Sensors like temperature and light sensors are used to produce voltage changes as inputs, while audio and light-based outputs like buzzers and LEDs require a voltage supply.

 

Specific components such as LEDs, switches, and piezo buzzers. LEDs are polarized and require a resistor in series to limit current flow, while switches can be used with a resistor or the Inpu_Pullup function to avoid floating inputs. Piezo buzzers do not require a resistor when used as an output, but a 1MΩ parallel resistor is needed when used to pick up a finger tap to avoid damaging the Arduino input. Thermistors are similar to LDRs and change resistance with temperature.

Smart systems and artificial intelligence are also used to develop recommender systems that provide users with personalized product or content suggestions based on their preferences and behavior. For instance, Amazon's recommendation system uses machine learning algorithms to suggest products to users based on their search history, purchase history, and ratings.

Sensors and embedded systems are widely used in modern technology, with Arduino being a popular platform for developing embedded systems. An example application is building a smart thermostat that uses sensors and AI to optimize energy usage and provide personalized recommendations. The embedded sensors and AI algorithms work together seamlessly to create an intelligent and efficient home automation system.

 

Overall, the text emphasizes the importance of caution and attention to detail when working with electronic components and provides practical information on their functions and applications.
