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. That’s 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 doesn’t 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. This is a suitable product for not only Grove users but also all electronics enthusiasts. So, buy now!
