Tutorials

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.

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.

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

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