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.

Power supply

We all know what power is, right? Okay, let's not assume; let's quickly go back to Chapter 2, Systems and Logic and refresh our knowledge about power. Come back here once you have read that.

All set? Great!

Now that we know what power is, let's find out why it is important to us. Arduino boards have an LED that switches on every time we connect with our computer, have you noticed that? No? Try it once, it will have a quick blink of some sort.

Every time you connect you Arduino board to the computer, you are powering it up. The USB port in the computer gives out 5 volts and some amount of current.


Find out how much current comes out of the USB port and write it down in your observation notebook.

An Arduino board typically functions on a 5V and 200mA power input. If the board is not given that much input, it won't power up at all, which means you won't be able to use it.

What happens if there is more current or voltage given to the board?

To make sure that the microcontroller gets...
