This book has been written to help absolute beginners learn how to create simple electronic devices controlled by an Arduino micro-computer. The book makes extensive use of the Proteus Visual Designer software, a unique product which allows users to program the Arduino using a simple flowchart, and then to simulate the operation of the program.Absolutely no prior knowledge of either electronics or computer programming is assumed making an ideal introduction to the subject for readers of all ages, especially those with a non-technical background.
