If you have already taken, or are in the process of taking my Arduino Step by Step Getting Started course, or if you already know the basics of the Arduino platform, then with a little practice you can create very interesting and fun projects on your own!

This project course is for anyone who wants to practice the design of simple gadgets based on the Arduino.

These projects will give you the opportunity to apply your knowledge of individual components and simple programming to design and make fun gadgets.

By the end of this course, you will have dramatically improved your skills and confidence in designing small Arduino-based systems. You will be able to go on and create your own gadgets.

Learning how to design a simple system requires you to think not just about the individual components, but also about how they will work together, how the end-user will interact with your gadget, and how to iterate from prototype to the final version.

In this course, you will practice simple system design by creating 10 gadgets of increasing difficulty.

If you have an Arduino and a few basic components, like environment sensors, an LCD screen, buttons and LEDs, then you are ready to get started with this course!

If you are excited about making simple gadgets with the Arduino, join many other Makers and me in Arduino Step by Step Getting Started – Projects!

PLEASE consider the list of prerequisites of this course carefully. If you are not familiar with any of the prerequisites, please consider enrolling to Arduino Step by Step Getting Started first. That course will help you prepare for this project course.

I really loved doing this course. The best thing about the course is that it makes you think and be creative. I think Peter's philosophy of learning by doing works very well. Quite often I found myself laying in bed thinking of different ways of writing a section of code. What is also very good is seeing how other people solve the same problems in such creative and inventive ways. I found I was highly motivated to complete my projects as I was interested in getting to the next stage of the module to see what Peter and the other learners had come up with. I highly recommend this course to anyone who is prepared to put the work in.

Take the knowledge you've learned from "Tech Explorations: Arduino Step By Step: Getting Started," and challenge yourself, by building projects from simple instructions.You are supplied with a list of components and a blueprint of what to build, then in each project, you must write a schematic (using Fritzing or the something similar) and an Arduino sketch that brings the project to life, as well as a picture or video showing how you built the project using your own skills. After each project submission, you can see how the instructor completed the project, and learn (if necessary), also getting feedback from the instructor and/or other students. Giving it 5-stars, because I'm really enjoying the format and challenge of this course. Another WIN from Tech Explorations!
