Welcome to Digital Logic & Interfacing
This module introduces the foundational principles of digital logic, the language of computers and microcontrollers. Unlike continuous analog signals, digital logic uses discrete binary values (0s and 1s) to process information. Understanding this is essential for designing control systems and interfacing with sensors and actuators. In this interactive guide, you will explore the building blocks of digital circuits, from simple logic gates to complex sequential circuits and communication protocols.
Learning Objectives
- Identify and describe the functionality of common logic gates.
- Apply Boolean algebra to simplify logic expressions.
- Differentiate between combinational and sequential logic circuits.
- Understand how microcontrollers use digital I/O and communication protocols.

Boolean Algebra Simplifier
Boolean algebra helps reduce complex circuits. Let's simplify the expression from the homework:
F = (A · B) + (A · B')
Sequential Logic: D Flip-Flop
A D Flip-Flop stores the value of input 'D' when the 'Clock' transitions. It "remembers" the state.
