Why learn about Logic?

Logic gates are not only at the heart of Digital Electronics, so you'll be controlling them or reading information from logic circuits when working with embedded software, they are also the foundation of conditional logic within software, "if (this AND that)" for instance.

There's also Boolean Algebra to understand too; the mathematics of Boolean calculations.

Having a good grasp on the basics of Logic Gates, Logic Circuits and Boolean Algebra are essential before moving forward on your journey into low-level / bare-metal embedded software.
