PCB Basics

What exactly IS a PCB? This tutorial will breakdown what makes up a PCB and some of the common terms used in the PCB world.

Alternating Current (AC) vs. Direct Current (DC)

Learn the differences between AC and DC, the history, different ways to generate AC and DC, and examples of applications.

Processor Interrupts with Arduino

What is an interrupt? In a nutshell, there is a method by which a processor can execute its normal program while continuously monitoring for some kind of event, or interrupt. There are two types of interrupts: hardware and software interrupts. For the purposes of this tutorial, we will focus on hardware interrupts.
