Overview of this book

LEGO BOOST is a feature-rich creative toolbox that helps kids to develop science, technology, engineering, and mathematics (STEM) skills in a fun way. The LEGO BOOST kit consists of motors, sensors, and more than 840 LEGO pieces to bring various multifunctional robots to life. This book will take you on an interesting and enjoyable journey where you will have fun building robots while developing your problem-solving and logical thinking skills. This book is an end-to-end guide that will take you from a beginner to expert level of robot building with LEGO BOOST and Scratch. Starting with the unboxing and a brief introduction to LEGO BOOST, you'll quickly get your first robotic model up and running. You'll understand how to use the electronic and non-electronic components and have fun building a range of intriguing robotics projects with increasing complexity and advanced functionality. Throughout the book, you'll work on a variety of amazing projects, such as building your own R2D2, a fictional character from Star Wars, that will pique your curiosity to learn robotics and help you explore the full potential of the LEGO BOOST kit. Once you've had fun working with the projects, you'll be introduced to an interesting challenge for you to solve by yourself! By the end of this book, you'll have gained the skills to build creative robotics projects with the LEGO BOOST creative toolbox, and have built on your logical thinking and problem-solving skills.

Let's code the robot without wheels

Open Scratch 3.0 and connect your BOOST Hub to your laptop as per the instructions given in Chapter 2, Building Your First BOOST Robot – Tabletop Fan. While performing some activities today, we shall understand the difference between seconds-based and rotation-based programming.

Before we move on to the task, let's learn about two new programming blocks:

  • set light color to: This block changes the light color of your BOOST Hub:

  • wait: This block waits for the number of seconds that the user inputs and lets the previous block execute for that time. We will learn how to use it while writing some code in the tasks. This block is found in the Control pallet:
