Summary
We learned a lot of important things in this chapter. Starting from how a microcontroller is made very similar to a human brain to what should be the approach towards coding a microcontroller. We then learned the importance of the power supply in Arduino, how it is very important to know the operating voltages on Arduino. We then learned how to use the Arduino software-some important parts of the software-and how to look up for help online. We learned about how a microcontroller works internally, and finally, we learned about what is open-source hardware and software. In the next chapter, we will learn how to finally take all the learnings into code and start working on our first project. I am super excited about this, are you too?
