Arduino for Kids

Overview of this book

The mission of this book is to integrate technology with the tools that children already use for crafts so that they feel that the technology is an extension of their playtime. We use coding, sensors, and micro-controllers integrated with art and craft supplies, origami, and Playdough. There are 10 fun-filled chapters that talk to children directly, and give clear instructions for non-technical parents too. We use Arduino as the controller of choice due to its easy availability and large community. By the end of the book, children will comfortably be able to set up their Arduino, read and understand code, manipulate code, and ultimately write their own code for projects. They will also be able to use basic sensors and know how components connect to each other. All the learning takes place with lots of colorful pictures and the circuits are neatly presented using wiring.

It's all about the logic

You may be wondering what it is with on and off, and how this translates into physical parameters or electrical signals. These will soon become clear.

We live in a world of analog signals-a countless number of colors that the eyes can see, a countless number of sounds we can hear, and a countless number of smells, and so on.

But with digital electronics, such as Arduino, we deal with discrete or distinct sets of values.

Logic levels, in a nutshell, describe the state that a signal is in. In digital electronics, such as Arduino, there are two logic states: 0 and 1. Since there are only two states, it is also called binary logic. This is also commonly translated to ON or HIGH for binary 1 and OFF or LOW for binary 0.

For Arduino, a HIGH signal is 5V, and LOW is 0V. This is how these logic levels manifest themselves physically in terms of voltage.

The Arduino uses these logic levels on its I/O pins to either take input from the outside world or give an output.
