A hookup guide for the HX711 load cell amplifier breakout board

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

An introduction to working with the Electret Mic Breakout Board.

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

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.

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

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

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.
