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.

Reading analog data


We mentioned earlier that the Arduino takes in digital data, which means that it can only handle numbers.

But what can we do for cases when we have an infinite number of possibilities, like light levels which cannot be quantified as a 0 or a 1, or ON and OFF?

Data like these which are continuous in nature, and do not have discrete or distinct levels are known as analog data. These signals in terms of voltage do not exist only at 0V or 5V, but vary between these two levels.

How do we go about reading such a continuous data then? Worry not, and remember, for all our problems, there's always a solution, we only need to think harder and explore.

ADC to the rescue!

An ADC, or an Analog-to-Digital converter is a circuit that converts voltages that are analog in nature to digital form.

The Arduino Uno has a 10 bit ADC inside it, which means it can convert an analog input voltage range, 0 to 5 volts, to a digital value between 0 and 1023 (2^10, hence 10-bit!).
