Introduction

This project demonstrates a line follower robot designed to navigate a path marked by a line on the ground. The robot uses sensors to detect the line and adjusts its movement accordingly to stay on course. This repository includes detailed instructions, code and a list of parts to help you recreate the project.

Features

• Autonomous navigation using line detection.
• Real-time sensor data processing.
• Accurate line tracking and following.

Hardware Requirements

To build the line follower robot, you will need the following components:

• Microcontroller (RP 2040)
• DC motors (4x)
• Line tracking sensors (5 IR sensors)
• Chassis (robot frame)
• Wheels (4x)
• Power supply (A battery pack with 4 AA batteries)
• Connecting wires
• Miscellaneous tools (screwdrivers and a lot of tape)

Software Setup

The following software tools are required to develop and upload the code to the microcontroller:

• Thonny IDE

Installation

1. Clone this repository to your local machine using:

git clone https://github.com/Xaristrike/Supernova.git

2. Install Thonny IDE on your operating system according to the instructions from Thonny's website.

Usage

1. Assemble the line follower.
2. Connect it to a computer and upload the code using Thonny IDE.
3. Place the robot on the line track.
4. Hold the "GP20" button for 3 seconds.
5. The robot will begin to move on the line.

Testing

1. Assemble the line follower
2. Connect it to a compujter and upload the code using Thonny IDE.
3. Hold the "GP21" button for 3 seconds. Make sure the line follower wheels are not touching the ground.
4. The motors will begin to slowly throttle up and down so you can see their performance.
