🔍 Project Overview

This project is an automated Smart Agriculture Robot designed to assist farmers with multiple farming tasks such as ploughing, seeding, watering, and soil monitoring. The system is built using an Arduino Uno, environmental sensors, servo mechanisms, and a Bluetooth communication interface.

The robot can be remotely controlled through a smartphone application via an HC-05 while also monitoring environmental parameters such as temperature, humidity, and soil moisture.

The collected data is displayed on a 16×2 LCD display, and automatic watering is activated when soil moisture levels drop below the safe threshold.

⚙️ How It Works (Short & Simple)

Mobile App Control
A smartphone sends commands like *forward, *Water, *Seed, etc., via Bluetooth to control robot movement and farming operations.

Robot Movement
Two DC motors controlled through motor driver pins allow the robot to move:

• Forward
• Backward
• Left
• Right
• Stop

Ploughing Mechanism
A servo motor lowers and lifts the ploughing tool to prepare the soil.

Seed Dispensing
Another servo controls the seed container, dropping seeds into the ploughed soil.

Watering System
A water pump and servo sprinkler irrigate crops when triggered manually or automatically.

Environmental Monitoring
A DHT11 measures temperature and humidity, while a soil moisture sensor monitors soil conditions.

Automatic Irrigation
If soil moisture is low, the system automatically activates the water pump.

Data Display & Transmission
Sensor data is displayed on the LCD and transmitted to the mobile device through Bluetooth.
