Are you working on a line following robot project? So you must be looking for a line finder? Since most of the automated robotic projects start from a line-following robot, it is very important to have a line finder device for such robots. Thats why we are presenting Grove Line Finder v1.1 for you. It consists of two parts an IR emitting LED and an IR sensitive phototransistor. When the phototransistor detects the reflected infrared light from the IR emitting LED, it will output a digital signal. This digital signal changes from HIGH to LOW. This Line Finder can output digital signal to a microcontroller, so the robot can reliably follow a black line on a white background or vice versa. The line finder works on TTL digital output mode. The output becomes HIGH when black is detected and LOW when white is detected.

The Grove Line Finder v1.1 is a small-sized device, so it doesnt require too much space on the project dashboard. You can also adjust its detecting range. It uses the LMV358 comparator and the RS-06WD photo-reflective diode to carry out the line following tasks. The Line Finder comes with a 4 pin Buckled Grove interface.

For all Grove users (especially beginners), Seeed Studio provides guidance PDF documents. Please download and read through Preface Getting Started and Introduction to Grove before using the product.
