What is Arduino?

The field of robotics is no longer just for scientists in labs. Today, kids and curious minds of all ages can tinker with circuits, write code, and bring robots to life! This exciting blend of electronics, programming, and creativity is where Arduino comes in.

What is Arduino?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. It’s designed for anyone making interactive projects, from students and hobbyists to engineers and artists. The Arduino board can read inputs—like a light on a sensor, a finger on a button, or a Twitter message—and turn it into outputs—activating a motor, turning on an LED, or publishing something online.

 

Why use Arduino for Robotics?

• Simplicity: Arduino is beginner-friendly with a simple programming language.
• Affordability: Arduino boards are relatively inexpensive.
• Community Support: A large community means many tutorials, forums, and resources.
• Versatility: From simple to complex, Arduino can be used for various projects.

 

Getting Started

What You Will Need?

• Arduino Board: The most common for beginners is the Arduino Uno.
• USB Cable: To connect your Arduino to your computer.
• Breadboard: For building circuits without soldering.
• Jumper wires: To connect components on the breadboard.
• Basic Components: LEDs, resistors, buttons, sensors, and motors.
• Arduino IDE: Software to write and upload code to your Arduino.

 

Setting Up Your Arduino

• Download and install Arduino IDE – https://www.arduino.cc/en/software
• Connect your Arduino: Use the USB cable to connect your Arduino board to your computer.
• Open the Arduino IDE: Launch the software and select your board type and the correct port under the ‘Tools’ menu.
• Upload Your First Program: The first program is usually the “Blink” example, which makes an onboard LED blink. Find it under File > Examples > 01. Basics > Blink, then click the upload button.

 

Building Your First Robot

Now that your Arduino is set up, let’s build a simple robot. We’ll make a basic line-following robot that follows a black line on a white surface.

 

Components Needed

• 2 DC motors
• Motor driver module (like the L298N)
• Line-following sensor module
• Chassis kit (with wheels and frame)
• Battery pack

 

Wiring the Robot

• Motors: Connect the motors to the motor driver module.
• Sensors: Attach the line-following sensors to the front of the robot chassis.
• Arduino and Motor Driver: Connect the motor driver to the Arduino using jumper wires.
• Power: Connect the battery pack to the motor driver module to power the motors.

Programming the Robot

Here’s a basic code example to get you started:
#define ENA 9
#define IN1 8
#define IN2 7
#define ENB 3
#define IN3 6
#define IN4 5
#define sensorLeft A0
#define sensorRight A1

void setup() {
  pinMode(ENA, OUTPUT);
  pinMode(IN1, OUTPUT);
  pinMode(IN2, OUTPUT);
  pinMode(ENB, OUTPUT);
  pinMode(IN3, OUTPUT);
  pinMode(IN4, OUTPUT);
  pinMode(sensorLeft, INPUT);
  pinMode(sensorRight, INPUT);
}

void loop() {
  int leftSensor = analogRead(sensorLeft);
  int rightSensor = analogRead(sensorRight);

  if (leftSensor < 500 && rightSensor < 500) {
    // Move forward
    digitalWrite(IN1, HIGH);
    digitalWrite(IN2, LOW);
    digitalWrite(IN3, HIGH);
    digitalWrite(IN4, LOW);
  } else if (leftSensor < 500) {
    // Turn right
    digitalWrite(IN1, LOW);
    digitalWrite(IN2, HIGH);
    digitalWrite(IN3, HIGH);
    digitalWrite(IN4, LOW);
  } else if (rightSensor < 500) {
    // Turn left
    digitalWrite(IN1, HIGH);
    digitalWrite(IN2, LOW);
    digitalWrite(IN3, LOW);
    digitalWrite(IN4, HIGH);
  } else {
    // Stop
    digitalWrite(IN1, LOW);
    digitalWrite(IN2, LOW);
    digitalWrite(IN3, LOW);
    digitalWrite(IN4, LOW);
  }
}

Beyond the Basics

As you gain confidence, you can explore more complex robotics projects.  Here are some ideas:

• Line Following Maze Solver: Build a robot that uses a line sensor to navigate a maze.
• Robotic Arm: This is a more advanced project that introduces the concept of servos (motors that rotate to specific positions) and allows you to build a robotic arm that can be programmed to pick up and move objects.
• Remote-Controlled Robot: Incorporate Bluetooth or Wi-Fi modules to control your robot wirelessly using a smartphone or joystick.
