Line Follower PCB Project

Overview

This repository contains the design files and code for a line follower robot. The project uses a line-following sensor (RLS sensor), a TB6612FNG motor driver, and an Arduino Nano to control the robot's movements.

Features

• Line-Following Capability: The robot can follow a predefined line path.
• Arduino Nano Control: Utilizes an Arduino Nano for processing sensor input and controlling the motor driver.
• TB6612FNG Motor Driver: Efficient motor driver for precise motor control.
• Custom PCB Design: Includes design files for a custom PCB to integrate all components neatly.

Hardware Components

• Arduino Nano
• RLS Line-Following Sensor
• TB6612FNG Motor Driver
• Motors and Wheels
• Power Supply (Battery)
• Custom PCB

Repository Contents

• PCB/: Contains PCB design files.
  • lschematic.pdf: Schematic diagram of the PCB.
  • layers.pdf: PCB layout diagram.
  • gerber.zip: Gerber files for PCB manufacturing.
• Code/: Contains the Arduino source code.
  • line_follower.ino: Main Arduino sketch for the line follower.
• Docs/: Additional documentation and resources.
  • bill_of_materials.xlsx: List of components required.

Getting Started

Prerequisites

• Arduino IDE: Download and install the Arduino IDE.
• PCB Manufacturing: Use the provided Gerber files to manufacture the PCB.

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/linefollower-pcb.git

2. Open the Arduino Sketch:
   • Open line_follower.ino in the Arduino IDE.
3. Upload the Code:
   • Connect your Arduino Nano to your computer via USB.
   • Select the correct board and port in the Arduino IDE.
   • Click the upload button to upload the code to the Arduino Nano.

Assembling the Robot

1. Manufacture the PCB:
   • Use the gerber.zip files to order the PCB.
2. Solder Components:
   • Solder the components onto the PCB.
3. Connect Motors and Sensors:
   • Connect the motors and the RLS line-following sensor to the PCB as per the schematic.
4. Power Up:
   • Connect a suitable battery to the PCB.

Usage

1. Place the robot on a track with a clear line to follow.
2. Turn on the power.
3. The robot should start following the line automatically.

Troubleshooting

• Not Following the Line:
  • Check sensor connections.
  • Ensure the line is clear and has good contrast with the background.
• Motors Not Running:
  • Verify motor connections.
  • Check the power supply.
