SparkFun Line Follower Array

SEN-13582 - SparkFun Line Follower Array

SparkFun Electronics

The SparkFun Line Follower Array is a long board consisting of eight IR sensors that have been configured to read as digital bits. The SparkFun Line Follower Arrays follow a dark line of about ¾ inch width or smaller (spray paint or electrical tape) on a light background. Each array features visible LEDs that point upward when the board is attached (properly) so you can see what the robot sees, brightness control right on the board, and an I²C interface for reading and power control. Here at SparkFun, the RedBot Shadow Chassis was used as a test platform but really this was designed as an add-on for almost any bot. The line follower functions by taking an 8-bit reading of reflectance for use with following lines or reading dark/light patterns and can see from about ¼ to ¾ inches away. The IR brightness control and indicator can be adjusted with the on-board potentiometer and can show you the strength of the IR LEDs.
