Robot using Arduino and Bluetooth Module (Obstacle Avoidance Robot)

This project is designed to build a robot that automatically detects the obstacle on its path and guides itself whenever an obstacle comes ahead of it. This robotic vehicle is built, using Arduino UNO board. An ultrasonic sensor is used to detect any obstacle ahead of it. A motor driver IC and 2 DC motors are used for controlling the movement of the robot. A servo motor is also used in this project. The ult ...

Arduino Irrigation and Plant Watering using Soil Moisture Sensor

This project is about a moisture-sensing automatic plant watering system using Arduino UNO. The system reads the moisture content of the soil using soil moisture sensor and switches ON the motor when the moisture is below the set limit. When the moisture level rises above the set point, the system switches off the pump.  The status of the tank, motor and the moisture level will be displayed on a 16×2 LCD di ...
