IoT: Control mediante MQTT, App Inventor y el ESP8266

El Internet de las Cosas (IOT - Internet of Things) permite amplios tipos de conexión, en este curso el Dr. Moutinho te muestra con su proyecto LED V1.0  cómo establecer control bajo el protocolo MQTT (Message Queue Telemetry Transport) y alternativamente, usando también App Inventor MIT. Las plataformas gratuitas permiten un amplio espectro de acción para la toma de decisiones (como se demuestra en los repositorios de las librerías de códigos).

La precisión y duración de este curso es suficiente para experimentar de inmediato y comprobar la flexibilidad del control M2M con la plataforma MQTT y P2M con la aplicación Android..

--- **Course Review for "App Inventor and MQTT Integration"** **Overall Rating:** 3.95/5.0 ### **Pros:** - **Comprehensive Resources:** Students can access the source files, which allows them to study, modify, and understand the code better. - **Code Quality:** The code provided in the course is generally well-written and serves as a good starting point for students. - **Flexibility with Learning:** Some users appreciate that they can find additional information on the internet that may offer better didactic resources. - **Discounts:** The platform offers various discounts, which are highly valued by students. - **Partially Exceeds Expectations:** For some learners, the course content exceeded their expectations, although with certain limitations. ### **Cons:** - **Incomplete Explanation:** The course does not thoroughly explain the code in App Inventor, only providing a copy of the program without adequate guidance or instruction. - **Expectations vs. Reality:** Some students had higher expectations for the course's content, particularly regarding simultaneous connections between App Inventor and MQTT brokers. The actual content did not always align with these expectations. - **Instruction Quality:** At least one review highlights the poor quality of explanations provided in the videos, suggesting that the course is closer to a YouTube video than a detailed Udemy course. - **Brief Videos:** A significant portion of the course material is presented in very short videos, which some students feel does not allow for in-depth learning. - **Lack of Integration Explanation:** There is criticism regarding the lack of comprehensive instruction on implementing the code, which could pose challenges for learners without prior knowledge of App Inventor. ### **Additional Notes:** - **Value for Money:** Some students believe that for the price point, the course offers a "regular" experience compared to other Udemy courses. - **Room for Improvement:** The course could be enhanced by providing more detailed explanations and a clearer explanation of the integration process between App Inventor and MQTT brokers. ### **Final Verdict:** The course **App Inventor and MQTT Integration** receives a solid rating but has room for improvement in terms of the quality of instruction and depth of content. Students who have prior knowledge or can supplement their learning with external resources might find more value in this course. Those expecting a comprehensive, detailed explanation of both the code and the integration process may be slightly disappointed but could still benefit from the provided material as a foundation to build upon.
