Arduino I2C LCD Python Demo

This project demonstrates how to control an I2C LCD display connected to an Arduino using the PyFirmata library.

Prerequisites

Before running this project, make sure you have the following:

• Arduino board
• I2C LCD display
• Python installed on your computer
• PyFirmata library installed (pip install pyfirmata)
• python 3.7 (PyFirmata works better with python 3.7)
• The following Arduino libraries installed:
  • LiquidCrystal_I2C
  • Wire
  • Firmata

Connection Diagram

• Gnd pin of the LCD to Gnd of the Arduino
• Vcc pin of the LCD to 5V of the Arduino
• SDA pin of the LCD to A4 of the Arduino
• SCL pin of the LCD to A5 of the Arduino

Installation

1. Clone this repository:

git clone https://github.com/akram-elgh/Arduino-I2C-LCD-Python-demo.git

2. Change into the project directory:

cd Arduino-I2C-LCD-Python-demo

3. Install the required dependencies:

pip install -r requirements.txt

Usage

1. Connect your Arduino board to your computer.
2. Upload the LCD_I2C_Firmata.ino sketch to your Arduino using the Arduino IDE.
3. Run the Python script: python main.py

Feel free to modify the main.py script to suit your needs and add more commands if necessary.
