This is a very basic course in using the arduino and having it communicate with various other devices. It is not a bad thing to have such a basic course exist, it is a good thing, but there are definite flaws in the course, the main ones being the grading system for the assignments and the lack of a place to go for clarification of the assignment / grading questions.

Both the penultimate and the final assignments require a certain amount of extra research and learning beyond what was taught in the lectures and yet the grading instructions for the assignments did not allow for taking that into account; the grading criteria was either binary (grade of 100%, or 0) or had the possibility of a partial passing grade but without listing a number of possible criteria that would put a project into the partial passing grade category.

I feel that the course did successfully help me to get started in this area of computing. My one disappointment was the removal of the traditional forums/discussions from the main body of the course, although it was possible to discuss things in a single discussion area. This made it less easy to discuss specific questions relating to your current assignment. As before I thought the practical demos were very good. I'm pleased I took the course - I wouldn't have made such good progress working on my own.

I hope the Raspberry Pi related courses reinstate the internal discussions - they add to the sense of a common goal being achieved and recover some of the things that aren't available in a MOOC where face to face student/professor interaction aren't available.

One of the drawbacks of this course is Peer Reviewed Assignment. It often ends up in plagiarism where one guy copies work of another. I was the victim twice in this course and it frustrates people like us and spoils the course. Also, some people review without going through the complete submission, like they just want to make the 3 numbers required for peer review. I strongly suggest to come up with better transparent system and different kind of assignments.

Overall, the course was good and I learnt new things.

Quick overview of the Arduino platform. Since I was new to Arduino, it helped me gather key concepts quickly and effectively. The peer-reviewed grading process is something that can be improved.

I think the course should have covered some more concepts in detail that are relevant to IoT devices - for example, interrupts and their usage, detailed discussion of the SPI protocol.

Also, more elaborate treatment of how to implement security in communication over internet with Arduino would have been great.

A really nice course which helps you learn how the sensor communicate with arduino. However a little shallow in approach towards wifi and ethernet shields.Week 4 was little superficial and not had depth about how to code and use library. But anyways a good course. A lot could be improved like providing more coding assignment and explaining how to use different shield. The basic approach is taught and it would be sufficient to start coding using sensors which are basic like pushbutton and leds.
