Introduction to the Internet of Things from edX

Internet of Things (IoT) is the present and the future of technology. Either, if you have none, few or some experience with electronics and you want to develop it projects this course will give you the necessary kick start to start creating amazing devices capable of sensing, controlling physical signals. This course introduces it using Arduino and ESP boards. This is a preliminary course in which we deal, with the basics of electronics and programming. If you already know the basics, then the second part of this course will be of your interest, in which we start creating smart devices.

Reviews summary

Intro to iot with arduino & esp

According to learners, this course serves as a solid introduction to the Internet of Things, particularly for those new to the field. Students praise its focus on basic electronics and programming concepts using popular hardware like Arduino and ESP boards. The hands-on exercises and final project are frequently highlighted as effective for practical application. However, the course is seen as very basic and may not provide sufficient depth for learners with prior experience in microcontrollers or electronics. Some also noted potential challenges with hardware setup and wished for more detailed coverage of specific topics.

Focuses on popular, accessible hardware.

"Using real boards like Arduino and ESP makes the concepts much more concrete."

"I appreciate that they focus on widely available and affordable hardware."

"Learning to program the ESP32 was particularly valuable for more complex projects."

Builds foundational electronics/programming skills.

"The sections on digital vs analog signals and basic coding for Arduino were very clear."

"I finally understand PWM and how simple circuits work thanks to this course."

"It gives you just enough electronics knowledge to understand the microcontroller interactions."

Helps apply theory with practical exercises.

"The small projects and final assignment were the best part, forcing you to actually build something."

"Actually connecting sensors and making them work based on the code was incredibly rewarding."

"I learned more from doing the labs than just watching the lectures."

Provides a clear starting point for IoT.

"If you are absolutely new to electronics and programming, this course is the perfect place to start."

"I had zero experience before this, and now I feel confident enough to tackle simple IoT projects."

"It really breaks down the intimidating concepts into easy-to-understand pieces."

Certain areas feel rushed or insufficient.

"I wish they spent more time on specific sensor types or communication protocols."

"PWM was explained, but I still feel I need more resources to truly master it."

"The final project guidance felt a bit minimal after the initial units."

Can be difficult to get hardware working.

"Troubleshooting the hardware setup took me longer than understanding the concepts."

"The course assumes you have the exact components, which isn't always easy."

"Getting the drivers and IDE configured properly was frustrating at times."

May be too simple for those with prior knowledge.

"As someone who had tinkered with Arduino before, the first few units were very repetitive."

"I was hoping for more advanced topics, but it really is strictly an 'Introduction'."

"If you already know C++ basics and simple circuits, much of this will be review."
