Arduino Robotics and Sensor Control Projects

(All the codes were written and tested on a Arduino UNO R3)

This repository contains a collection of beginner-friendly Arduino projects focusing on robotics and sensor-based control systems. Each project demonstrates the use of Arduino for real-world applications, including LED control, motor control, ultrasonic distance measurement, and Bluetooth-based robot control. The goal is to provide simple and modular examples to help others learn and experiment with Arduino programming and hardware integration.

Projects Included

1. LED Blink Test

• Description: A basic sketch to test the blinking functionality of an LED using Arduino. The LED blinks at a fixed interval to demonstrate basic output control.
• Features:
  • Blinks an LED connected to a digital pin.
  • Adjustable delay intervals.

---

2. Line Following Robot Control

• Description: A line-following robot that uses two sensors to detect and follow a line on a surface. The motors adjust based on sensor input to keep the robot on track.
• Features:
  • Reads input from left and right sensors.
  • Controls motor directions for forward, backward, and turning movements.

---

3. Bluetooth-Controlled Robot

• Description: A robot controlled via serial commands, such as those sent from a Bluetooth terminal or Serial Monitor. Commands like 'F', 'B', 'L', and 'R' dictate the robot's movement.
• Features:
  • Serial communication to receive commands.
  • Motor control for forward, backward, left, and right movements.

---

4. Ultrasonic Distance Measurement

• Description: A sketch to measure distance using an ultrasonic sensor. It calculates the time taken for sound waves to travel to an object and back, converting it into a distance reading.
• Features:
  • Trigger and echo functionality using ultrasonic sensors.
  • Real-time distance measurement displayed on the Serial Monitor.

---

5. Ultrasonic Obstacle Detection and Motor Control

• Description: Combines ultrasonic distance measurement with motor control for a simple obstacle detection system. If an obstacle is detected within 100 cm, the robot stops; otherwise, it moves forward.
• Features:
  • Real-time distance measurement using an ultrasonic sensor.
  • Conditional motor control based on proximity to objects.
