A: No. The book requires high school algebra. Calculus is mentioned but clearly marked as "optional deep dive."

This is the "meat" of the book, covering everything from 555 timers to complex microprocessors.

It introduces the basics of FPGAs and CPLDs, which are becoming increasingly common in high-level DIY projects.

A refresher on voltage, current, resistance, and the mathematical laws (Ohm’s and Kirchhoff’s) that govern them.

Here's a sample piece from the book to give you an idea of the content:

: Includes practical instructions on drawing schematics, prototyping on breadboards, and creating PCBs. It also details the use of test equipment like multimeters and oscilloscopes. Modern Modules

Chapters dive into the "why" behind electric current, voltage, and resistance using helpful water analogies to simplify complex concepts.
