Features

Emotion-Based Color Selection: Detects postive, negative, or neutral mood of text and changes LED colors based on user input.

Hardware Integration: Uses Arduino to control NeoPixel LED lights.

React Frontend: Interactive UI for text input.

Node.js Backend: Handles communication between frontend and Arduino and API calls.

Technologies Used

Frontend: React.js

Backend: Node.js, Express

Hardware: Arduino, NeoPixel LED

Setup Instructions

Hardware Setup

1. Connect NeoPixel LEDs: Connect the NeoPixel LED strip to the Arduino using three wires:
   • GND → Ground
   • 5V → Power
   • Data In → Control Signal

Software Setup

1. Install Dependencies

npm install

1. Run the Backend Server

node server.js

1. Start the Frontend

cd client
npm start

How It Works

User Input: The user inputs text and the app analyzes the sentiment - it changes the light accordingly.

Backend Processing: The Node.js backend determines mood.

Lighting Effect: The LED strip changes colour based on mood.

Future Enhancements

Implement voice emotion detection.
