    • Suitable for creative projects like interactive clothing and soft circuits.

Key Features of Arduino Boards

  • Microcontroller: The main processing unit (such as ATmega328P or ATmega2560) that executes code and controls inputs/outputs.
  • Digital I/O Pins: Used for interfacing with sensors, actuators, LEDs, and other electronic components.
  • Analog Input Pins: Used for reading analog signals, such as sensors that provide varying voltage levels.
  • USB Interface: For programming the board and communication with a computer.
  • Power Supply: Can be powered through USB, an external power supply, or a battery.

Applications of Arduino Boards

  • Prototyping: Rapid prototyping of electronic circuits and projects.
  • Robotics: Used in robots to control motors, sensors, and communicate with other devices.
  • Home Automation: Monitoring and controlling home appliances like lights, fans, and security systems.
  • IoT Projects: Connecting sensors and devices to the internet for remote monitoring and control.
  • Wearable Electronics: Used in projects like interactive clothing and health trackers.
  • Education: Widely used to teach electronics and programming to students.

Advantages of Arduino Boards

  1. Ease of Use: Beginner-friendly, with a large community and extensive resources like tutorials and example codes.
  2. Open Source: Both hardware and software are open-source, allowing for customization.
  3. Versatility: Suitable for a wide variety of applications, from simple LED blinkers to complex automation systems.
  4. Affordable: Relatively low cost, making it accessible for hobbyists and students.

Arduino Software (IDE)

The Arduino IDE (Integrated Development Environment) is the software used to write and upload code to an Arduino board. It uses a language based on C/C++, and the IDE provides built-in functions for handling inputs, outputs, and other operations. The Arduino IDE also has a library manager, allowing users to add pre-written code to interact with sensors, modules, and other components easily.

Arduino is popular for creating interactive projects and prototyping, thanks to its simplicity and flexibility. It is used in countless projects, ranging from simple tasks like turning on an LED to advanced applications such as home automation, robotics, and IoT devices.

1.Using an LDR (Light Dependent Resistor) with Arduino to Measure Light Intensity

 Using an LDR (Light Dependent Resistor) with Arduino to Measure Light Intensity. Components Needed: Arduino board LDR (photoresistor) 10kΩ resistor Breadboard and jumper wires Circuit Connections: LDR : Connect one leg of the LDR to 5V on the Arduino, and the other leg to an analog input pin (e.g., A0). Resistor : Connect a 10kΩ resistor between the LDR leg (that goes to the analog pin) and GND. This forms a voltage divider. Explanation: When light falls on the LDR, its resistance changes, affecting the voltage at the analog pin. The analog pin reads a value between 0 and 1023 depending on the light intensity. Example Code: C++ Code int ldrPin = A0; // Analog pin to which LDR is connected int ldrValue; void setup () { Serial. begin ( 9600 ); // Start the serial communication to view the LDR value } void loop () { ldrValue = analogRead (ldrPin); // Read the LDR value Serial. println (ldrValue); // Print the value to the Serial Monitor delay ( 500 ); // Delay for...
