For kids and senior EE’s, this book offers a unique way to explore computer logic gates. With just two buttons and an LED, the book teaches about six basic logic gates: WIRE, NOT, OR, AND, XOR, and a LATCH. What makes this book truly clever is its use of light sensors to detect which page is open, adjusting the operands accordingly. If you fit into any of the categories listed, such as having a baby, planning to have one, being interested in computer engineering, or knowing someone who fits the bill, this book is definitely worth considering. No controversial information or surprising content is mentioned.
