What (LCD, motor, sensor) are you trying to interface with?
The "Evil Genius" theme adds a fun, mad-scientist narrative to the learning process. You will build everything from simple flashing LEDs to complex robotics components, sound generators, and sensor arrays. Key Topics Covered
★★★★☆ (4/5) – Essential reading, provided you have the patience to adapt the toolchains to the modern era.
: Tweaks and modifications suggested by the author to test your understanding. How to Build Your "Evil Genius" Lab What (LCD, motor, sensor) are you trying to interface with
: The experiments start with absolute basics, meaning you do not need previous programming experience to begin.
The book is structured to take a complete beginner from blinking a simple Light Emitting Diode (LED) to developing complex systems involving sensors, motor control, and liquid crystal displays (LCDs). Core Themes and Topics Covered:
To follow along with the 123 experiments safely and effectively, you will need a basic hardware toolkit: Tool / Component The book is structured to take a complete
Unlike academic textbooks that drown the reader in theory before touching a wire, Predko’s approach is ruthlessly pragmatic. The experiments are designed to be built. The early chapters strip away the complexity of the Microchip PIC architecture, forcing the user to blink an LED—the "Hello World" of hardware. By experiment #10, the reader is no longer reading; they are debugging.
The 2021 edition is protected by copyright. While "evil genius" might imply sailing the high seas, the PDF is legally available for purchase via McGraw-Hill’s online store, RedShelf, and VitalSource (often for under $25). Buying the PDF gives you clickable schematics and searchable code—well worth it.
First, let’s address the elephant in the room: The original book was authored by and published in 2004, focusing on the PIC16F84 and PIC16F628—classic, but dated by modern standards. So why the buzz around a 2021 PDF? But little did he know

The following article explores what makes this book a classic, what you will learn from it, and how to set up your own laboratory. What is the Book About?
But little did he know, a hero was watching from the shadows. A brilliant engineer, known only by her handle "Lady Byte," had been tracking The Evil Genius's progress. She had a secret plan to infiltrate his lair and sabotage his microcontroller army.
The answer lies in context. The typically refers to scanned and digitally enhanced versions of the original text, often bundled with updated supplemental files created by the online community in 2021. These supplements include:
