Learn the difference between 3.3V and 5V devices and logic levels.
Si4707 Hookup Guide
Instructions on hooking up to and communicating with the Si4707 Weather Band Radio Breakout using an Arduino.
How to Use a Breadboard
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.
Getting Started with the LilyPad MP3 Player
The LilyPad MP3 Player is an amazing little board that contains almost everything you need to play audio files. You can use it to create all kinds of noisy projects, from MP3 hoodies to talking teddy bears. Your imagination is the only limit! This tutorial will help you 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.
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.
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.
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.
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.
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.
