Summary
This has been our first real work project, and I've shown you quite a good bunch of concepts and procedures.
We have considered the breadboard as our sandbox, where we will try to connect every circuit we are going to build throughout the book and in your daily work with Arduino.
We have connected our first component to the Arduino board through a digital output and have met the power connections of our circuit.
Finally, we have had our first real contact with an Arduino program written in the C programming language. We have recognized the essential parts of any Arduino sketch and learned the basic syntax of the C language and its most important particularities.
In the next chapter, we will learn about analog outputs, which will introduce us to a very powerful transistor-based circuit that will allow us to deal with no less than a DC motor. On the programming side, we will meet another very interesting structure to step along a range of values. This is getting interesting, isn't it?
