Electrical Engineering

Welcome to the wonderful world of breadboards. Here we will learn what a breadboard is and how to use one to build your very first circuit.

A diode primer! Diode properties, types of diodes, and diode applications.

Picking up where we left off in "Getting Started with LTSpice," we delve a little deeper into LTSpice through an introduction of Operational Amplifiers (OpAmps).

The essential parts for beginning (or even experienced) hobbyists that gives you all of the basic through-hole components you will need to get started playing with embedded projects. We'll identify a few parts in the kit and provide a few basic circuits to get started!

A tutorial on electronics' most overlooked and underappreciated component: the switch! Here we explain the difference between momentary and maintained switches and what all those acronyms (NO, NC, SPDT, SPST, ...) stand for.

A tutorial on all things resistors. What is a resistor, how do they behave in parallel/series, decoding the resistor color codes, and resistor applications.

Get to know the contents of the SparkFun Discrete Semiconductor Kit.

A tutorial about different ways to reduce the current draw for your next Arduino project the easy way.

A crash course in bi-polar junction transistors. Learn how transistors work and in which circuits we use them.

Not working as expected? In this tutorial, we will be exploring a few general troubleshooting tips and possible solutions that frequently come up with SparkFun's Technical Support.

Getting started with the SparkFun Proto Pedal. We'll assemble the board, then discuss some of the details of the circuit.

Building a gyrator-based analog equalizer using the Proto Pedal.

Building a pedal around the Teensy 3.2 and Teensy Audio shield. Changing the effect in the pedal is as easy as uploading a new sketch!

In this article, we share our recent advancements in quality control. Along with making our tests more thorough, we have also made them more efficient and robust.

How to strip, crimp, and work with wire.

Learn about Ohm's Law, one of the most fundamental equations in all electrical engineering.

Learn the basics about LEDs as well as some more advanced topics to help you calculate requirements for projects containing many LEDs.

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.

An introduction to polarity in electronic components. Discover what polarity is, which parts have it, and how to identify it.

We can see electricity in action on our computers, lighting our houses, as lightning strikes in thunderstorms, but what is it? This is not an easy question, but this tutorial will shed some light on it!
