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.
How to hook up and use the OpenSegment display shield. The OpenSegment is the big brother to the Serial 7-Segment Display. They run on the same firmware, however the OpenSegment is about twice as big.
Installing Arduino IDE
A step-by-step guide to installing and testing the Arduino software on Windows, Mac, and Linux.
Creating a Humidor Control Box
Because some of our boards need to be re-humidified after reflow, we decided to make our own humidor. This tutorial will focus on how to model a project in 3D and then fabricate it using a CNC routing machine.
Programming the pcDuino
With great power comes great complexity. This tutorial will teach you some of the basic concepts needed to get the most out of programming your pcDuino.
The Uncertain 7-Cube
The Uncertain 7-Cube is a non-committal, less-than-helpful, but also entirely honest fortune teller. Simply ask it a yes or no question, give it a nudge, and the 7-Cube will dutifully inform you that it doesn’t have all the facts and doesn’t feel comfortable making a guess.
pcDuino Hookup Guide
pcDuino is SparkFun's single-board hardware-hacker based mini PC. It comes with Linux pre-installed, has all the hardware functionality of an Arduino Uno, and can be programmed almost as easily as an Arduino!
Light is a useful tool for the electrical engineer. Understanding how light relates to electronics is a fundamental skill for many projects.
LDK Experiment 1: Lighting Up a Basic Circuit
The first experiment in the LilyPad Design Kit series. In this exercise, you will learn how a basic e-textiles circuit works, and light up a sewable LED using a coin cell battery holder and conductive thread.
Binary is the numeral system of electronics and programming...so it must be important to learn. But, what is binary? How does it translate to other numeral systems like decimal?
This tutorial explains how common IR communication works, as well as shows you how to set up a simple IR transmitter and receiver.
What is a Circuit?
Every electrical project starts with a circuit. Don't know what a circuit is? We're here to help.
The basics behind the batteries used in portable electronic devices: LiPo, NiMH, coin cells, and alkaline.
A quick introduction to pull-up resistors - whey they're important, and how/when to use them.
