Chapter 5. Arduino and Sensors

If you have gotten this far, I congratulate you for your performance and eagerness to learn. In this chapter, we will learn interesting topics such as:

  • How to create, use, and find libraries
  • New sensors and components for our system, such as LCD
  • More hardware
  • Debugging

Besides all this, we will strengthen certain aspects. From a more practical perspective, we will use concepts that we've previously seen.

As you recall, resistors and capacitors are the essential elements in the circuits. Now, I want to show you a new property. It is an input to the RC (resistor-capacitor) circuits.

We will discuss this point in more detail. I encourage you to find out more about these issues and visit the linked information. Capacitors can ...
