LED Controller with Gesture Recognition

This project demonstrates controlling multiple LEDs connected to an Arduino board using Python and the pyFirmata library. The Python script communicates with the Arduino board via serial communication to turn the LEDs on or off based on hand gestures detected using the Mediapipe library.

Prerequisites

Before running the project, make sure you have the following prerequisites installed:

• Python 3.x
• pyFirmata library (pip install pyfirmata)
• Arduino IDE

Additional Libraries

In addition to the prerequisites mentioned above, you'll need to install the following Python libraries:

• mediapipe library for hand gesture recognition (pip install mediapipe)
• opencv library for capturing video (pip install cv2)

Getting Started

1. Upload Arduino Sketch:

   • Open the Arduino IDE and save the standard firmdata file and save it to the connected arduino board.

2. Connect Hardware:

   • Connect the LEDs to the digital pins on your Arduino board as specified in the Arduino sketch.
   • Connect the Arduino board to your computer via USB.

3. Run Python Script:

   • Open a terminal and navigate to the directory containing the Python script (main.py).
   • Run the Python script:

     python main.py
     

Usage

• Use hand gestures to control the LEDs connected to the Arduino board.
• The Python script uses the mediapipe library to detect the number of fingers raised and maps it to the corresponding number of LEDs to turn on.
