The book explores both Assembly language and C programming , giving you a choice between low-level control and high-level efficiency. Highlights of the 123 Experiments
A large breadboard for temporary circuits.
Precise angle manipulation for automated arms or printing mechanisms.
By the time you reach the final experiment, you won't just be following instructions—you’ll be designing your own "evil" inventions from scratch. Share public link The book explores both Assembly language and C
The book focuses on the Microchip PIC architecture, specifically the PIC16F series (notably the PIC16F84A and later the PIC16F627/628). These chips are historically significant as the training grounds for a generation of engineers.
Standard LEDs, tactile push-buttons, a 4x4 matrix keypad, a standard 16x2 character LCD character module (HD44780 compatible), and small DC or stepper motors.
You will interface the PIC with 7-segment LEDs, learning how to use lookup tables in Assembly to convert binary numbers into the specific segment patterns required to display numerals 0 through 9. By the time you reach the final experiment,
The "Evil Genius" series is famous for its "learn by doing" philosophy. Instead of spending chapters on silicon physics, the book throws you straight into the lab. Every experiment builds on the last. Code Focused: It covers both Assembly and C programming.
