An introduction to working with the Electret Mic Breakout Board.

An introduction and getting started guide for the Battery Babysitter - a flexible LiPo battery charger and monitor.

Build a portable gas monitor to check for dangerous levels of hazardous gases.

A brief history of how ASCII came to be, how it's useful to computers, and some helpful tables to convert numbers to characters.

This is a guide for assembling and basic use of the Beefcake Relay Control board

Learn how to build a remote water level sensor for a water storage tank and how to automate a pump based off the readings!

Use an Arduino and the SparkFun Sound Detector to create visualizations on Addressable RGB LED strips.

Use GPS to have two objects, a base and a target, point towards one another. This can be used to aim a directional antenna (or in the case of this project, a laser) from one object to the other object at a distance that is only limited by your ability to provide the base station with the target's GPS location.

Learn how to build a wireless controller to kill power when things go... sentient.

How to use the SparkFun Continuous Rotation Servo Trigger with continuous rotation servos, without any programming!

Looking under the hood of the Servo Trigger -- using the development environment and some finer details of the firmware.

Servos are motors that allow you to accurately control the rotation of the output shaft, opening up all kinds of possibilities for robotics and other projects.

This is a quick guide to using the Google Science Journal app with the Arduino 101 that's included and pre-programmed in the SIK for Google's Science Journal App.

Turn the Intel® Edison into an access point that serves a simple browser-based game. High scores from the game are displayed on a character LCD.

Get started using the IOIO-OTG with your Android device or PC.
