SparkFun Line Follower Array Hookup Guide
Learn how to connect the RedBot Line Following Sensor Bar to an arduino type microcontroller. Use the example sketches to read data from the bar, and try out a simple line following algorithm.
SoftPot Hookup Guide
Equip your Arduino project with a sliding soft potentiometer to monitor position or adding linear control to your project.
GPS Differential Vector Pointer
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.
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.
