Overview
This repository contains the hardware design files for a Line Following Sensor module. It includes the complete schematic and Printed Circuit Board (PCB) layouts necessary to manufacture and assemble the sensor array, which is commonly used in line-follower robots and automated guided vehicles (AGVs).
Features
- Sensor Array: Hardware design for detecting contrasting lines (e.g., black line on white surface).
- KiCad Design: Fully designed using open-source KiCad EDA.
- Ready for Manufacturing: PCB layout files provided for easy fabrication.
Repository Contents
Schematic.kicad_sch: The KiCad schematic file detailing the circuit connections and components.PCB.kicad_pcb: The KiCad board layout file for PCB manufacturing.Schematic_page.jpg/Screenshot: Visual references of the schematic and circuit design.README.md: Project documentation.

Questions
What parts does the LineFollowing Sensor use?
50 parts, built around the TCRT5000 and CD74HC4067M. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the LineFollowing Sensor KiCad files?
From the BRaj36001k/LineFollowing-Sensor repository on GitHub, at the commit this page was made from: the board is PCB.kicad_pcb and its schematic Schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LineFollowing Sensor design in my own project?
Its repository states no licence, so its author keeps all rights: ask BRaj36001k before reusing the design.
