I have written OER textbooks for most of my classes. Each one is featured on this page. Eventually (2023 or 2024?) each class lab manual will be released as an OER text as well. Please check back at that point for links to those textbooks.

Microcontrollers by Alyssa J. Pasquale, Ph.D.


This book covers microcontrollers with a focus on the ATmega328P microcontroller (both with and without the Arduino Uno platform), programming in C and assembly. Topics include microcontroller fundamentals, parallel and serial I/O, memory and memory addressing, analog to digital conversion, interrupts, clock and timer/counters, and basic PI control systems and feedback.

Digital Systems by Alyssa J. Pasquale, Ph.D.

Digital Systems

This book covers the principles of digital logic design and includes example circuits using the 7400 series of TTL logic chips. Topics include number systems and conversions, binary arithmetic, Boolean algebra, expression simplification (K-maps, Quine-McCluskey), circuit optimization, timing, logic devices (MUX, decoders, etc.), sequential circuits, registers and counters, and finite state machines.

Circuit Analysis by Alyssa J. Pasquale, Ph.D.

Circuit Analysis

This book covers linear analog circuit design. Topics include circuit laws and theorems (Ohm’s law, Kirchhoff’s laws, source transformation, superposition, Thevenin and Norton’s theorems), operational amplifiers, capacitance and inductance, RL and RC circuits, second order circuits, phasor transforms, AC power, Laplace transforms, transient and steady-state analysis.

Circuit Analysis Solutions by Alyssa J. Pasquale, Ph.D.

Circuit Analysis Solutions

This book contains step-by-step instructions to solve each of the end of chapter examples in the Circuit Analysis textbook.
