| How to Use an Oscilloscope | |
| Have you ever found yourself troubleshooting a circuit, needing more information than a simple multimeter can provide? If you need to uncover information like frequency, noise, amplitude, or any other characteristic that might change over time, you need an oscilloscope! | |

| What is an Arduino? | |
| Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board. | |

| IR Communication | |
| IR, or infrared, communication is a common, inexpensive, and easy to use wireless communication technology. IR light is very similar to visible light, except that it has a slightlty longer wavelength. This means IR is undetectable to the human eye - perfect for wireless communication. For example, when you hit a button on your TV remote, an IR LED repeatedly turns on and off, 38,000 time a second, to transmit information (like volume or channel control) to an IR photo sensor on your TV. | |

| How to Use a Multimeter | |
| So… how do I use a multimeter? This tutorial will show you how to use a digital multimeter (DMM), an indispensable tool that you can use to diagnose circuits, learn about other people’s electronic designs, and even test a battery. Hence the ‘multi’-‘meter’ (multiple measurement) name. We will be using the SparkFun VC830L throughout the tutorial but these methods should apply to most multimeters. | |

| Resistors | |
| Resistors - the most ubiquitous of electronic components. They are a critical piece in just about every circuit. And they play a major role in our favorite equation, Ohm’s Law. | |

| Boss Alarm | |
| t’s a common occurrence in any office – you’re on Facebook or browsing SparkFun when all of a sudden your boss walks in to see that you’re not working. This project aims to avoid that embarrassment and frowns from management. The Boss Alarm alerts you of anyone walking into your office and automatically changes the active program on your computer. The sensors are inconspicuously hidden in cute woodland creatures that are guaranteed to brighten up your office and definitely not creep out any of your coworkers! |

| Robot Journal - Pamela | |
| SNAK: Stealthy/Silent Ninja Android Killer Okay, my robot wasn’t exactly silent, but it was kind of stealthy (if slowness equates to stealthiness). It's also a play on words for Snack, because Android releases are based on tasty treats – in my case, Ice Cream Sandwich. To save you from falling asleep or getting the munchies, I’ll get off the topic of food and get on with the tutorial. The day I was told we were making robots for our bonus goals, I went home and dreamed of lasers, rail guns, chemicals and an assortment of other deadly weapons to melt my fellow coworkers' robots. As long as it doesn’t hurt a human, Asimov would eagerly approve, right? My heart was broken when I found out we could only destroy small toothpicks attached to our robots for the competition, and that we had some tough specifications to meet. Our robots had to fit in a 6x6-inch box and weigh no more than 1.5 pounds. How was I supposed to add all of my weapons with that kind of weight restriction? It's probably for the best; my suggestions of such weapons were not looked highly upon, certainly out of fear of seeing little cute bots melt into a puddle of acrylic and metal bits in the arena. For the record, lasers can be really safe, especially when you’ve got a “kill” switch. All things said, there would have been safety goggles required for everyone watching the battle if I were allowed to go this route. |

| Blynk Board Washer/Dryer Alarm | |
| This tutorial demonstrates how to pair the Blynk Board with an MMA8452Q Accelerometer Breakout to create a shake-sensing laundry monitor. Once the laundry is done, the electronics will communicate with the Blynk app – over Wi-Fi – to send your phone a push notification. | |

| Photon Remote Temperature Sensor | |
| Photon Remote Temperature Sensor The scientific method allows us to examine the universe and its natural phenomena. Through collection and analysis of data, we discover historical trends to make predictions about future events. One such phenomenon that greatly impacts our daily, and long-term, lives is temperature. This tutorial shows you how to build your own remote temperature sensor that automatically uploads data to the data.sparkfun.com web service. This is a perfect, hands-on project for teaching, or learning, the difference between daily temperature fluctuations and average temperature over time, a particularly crucial distinction when discussing climate change. This system uses the Particle Photon as the control device, a handy lil' microcontroller that easily connects to WiFi. The Photon reads in temperature data from the SparkFun TMP102 digital temperature sensor, then uploads the data to a web server for remote data acquisition and, if desired, subsequent analysis and plotting. |
