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.

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.

LTspice is a high performance SPICE simulator, schematic capture and waveform viewer with an impressive library of passive devices. Over 1000 models are included in the download but you can also add third party models.
