This book is designed to promote technology literacy through an easy introduction to microcontroller programming and simple robotics. Are you a middle-school student? You can be successful by following the check-marked instructions with your teacher’s support. If you are a pre-engineering student, push yourself a little farther, and test your comprehension and problem-solving skills with the questions, exercises and projects (with solutions) in each chapter summary. If you are an independent learner working on your own, go at your own pace and check in with Parallax’s Robotics forum if you get stuck.
