# ARDUINO-I2C-MOTOR
Arduino-Based Motor Control System with I2C Communication
# 📜 **Arduino-Based Motor Control System with I2C Communication** 🚀
🎉 **Developed using Arduino & Proteus for learning and experimentation!** 🔥🚀
## 🎯 **Project Overview**
This project demonstrates **DC motor speed and direction control** using **two Arduino boards** that communicate via **I2C protocol**. The system uses a **potentiometer** as an input, and a **motor driver** (L293D/BTS7960) to drive the motor. Additionally, an **LCD display** shows real-time voltage values.
---
## ⚙️ **System Workflow**
🔹 **Arduino 1 (Master)** reads input from a **potentiometer** (-5V to +5V).
🔹 **I2C Communication** sends the processed voltage data to **Arduino 2 (Slave)**.
🔹 **Arduino 2 (Slave)** controls the **motor driver** using **PWM** signals.
🔹 **Motor driver** generates an output voltage of **-12V to +12V** based on input.
🔹 **LCD Display** shows the input and output voltages in real time.

## 🔌 **Components Used**
- 🎛 **Arduino 1 (Master)** – Reads potentiometer values & transmits via I2C.
- 🎛 **Arduino 2 (Slave)** – Receives data, controls motor driver & updates LCD.
- 🎚 **Potentiometer** – Provides adjustable voltage input.
- ⚡ **Motor Driver (L293D/BTS7960)** – Amplifies Arduino output for motor control.
- 🔄 **DC Motor** – Controlled using PWM for speed & direction.
- 📟 **LCD Display (JHD-2X16-I2C)** – Displays input & output voltages.
- 🔌 **I2C Communication Wires** – Connect SDA & SCL pins between Arduinos.
- 🔧 **Pull-up Resistors (4.7kΩ)** – Ensures proper I2C communication.

## 🔗 **Circuit Connections**
### **📌 Arduino 1 (Master)**
✅ **Potentiometer → A0**
✅ **SDA (A4) & SCL (A5) → Arduino 2 (Slave)**
✅ **GND → Shared with Arduino 2**
### **📌 Arduino 2 (Slave)**
✅ **SDA & SCL → Arduino 1**
✅ **Motor Driver → Motor Pins & PWM Control**
✅ **LCD Display → I2C Communication (SDA & SCL)**

## 🔬 **I2C Communication - Hardware Level Understanding**
📡 **I2C (Inter-Integrated Circuit)** is a serial communication protocol that uses:
✔️ **SDA (Serial Data Line)** – Carries the data bits.
✔️ **SCL (Serial Clock Line)** – Synchronizes data transfer.
### **🛠 How It Works:**
1️⃣ **Arduino 1 (Master)** initiates communication & sends input voltage.
2️⃣ **Arduino 2 (Slave)** receives data & maps it to motor control logic.
3️⃣ **Motor driver** controls the motor using **PWM signals**.
4️⃣ **LCD** displays **real-time voltage readings**.
🔹 **Precision Handling:** Data transmission maintains **0.01V accuracy**.
🔹 **Pull-up Resistors (4.7kΩ)** are used for stable I2C communication.

## 🖥 **Software Implementation**
✔️ **Arduino 1 (Master):**
- Reads **analog input from potentiometer**.
- Maps input voltage range **(-5V to +5V)** to **(0-255) for I2C transmission**.
- Sends data to Arduino 2 via **I2C protocol**.
✔️ **Arduino 2 (Slave):**
- Receives data & converts it back to voltage range **(-12V to +12V)**.
- Uses **PWM** to control the motor driver for speed & direction.
- Updates the **LCD display** with real-time voltage readings.
