🔧 Arduino Basics – Getting Started with Components

💡 Welcome to Arduino Basics, a collection of simple and fun projects designed to help you get familiar with Arduino hardware and programming!

Each example introduces a new component or concept, making it easy for beginners to learn step-by-step.
Whether you're blinking your first LED or playing tones with a buzzer, this repo will help you build a strong foundation in embedded electronics.

More components will be added regularly — stay tuned for updates! 🔁

⚙️ Requirements

• Arduino IDE → Download here
• Arduino Board → Uno, Nano, or Mega recommended. I used Uno for most of the projects!
• Basic Components → LEDs, resistors, push buttons, jumper wires, breadboard, sensors, potentiometers, piezo buzzers etc.
• USB Cable to connect your Arduino

New components might be added with new projects!

📦 Prerequisites

• Arduino IDE (version 1.8.x or higher) or Arduino Web Editor
• Basic understanding of C/C++ programming
• Fundamental knowledge of electronics (voltage, current, resistance)

🚀 Projects Overview

• Morse Code for SOS -Generates an SOS distress signal (··· --- ···) using basic digital write commands. This project introduces digital output control and timing.

  Key Concepts: digitalWrite(), delay(), digital pins

• Morse Code for SOS (Minimized) - An optimized version of the SOS signal using functions or loops to reduce code repetition.

  Key Concepts: Functions, code optimization, DRY principle

  (Both the above projects use the on-board Arduino LED)

• LED Glow - The classic "Hello World" of Arduino - makes an LED blink on and off.

  Key Concepts: Basic I/O, pinMode(), digital output

• LED Intensity Variation - Controls LED brightness using Pulse Width Modulation (PWM).

  Key Concepts: analogWrite(), PWM, duty cycle

• LED Morse Code for SOS - Combines LED control with Morse code timing to create a visual SOS signal.

  Key Concepts: Pattern generation, timing sequences

• Buzzer - Basic buzzer control - creating simple sounds and tones.

  Key Concepts: tone(), noTone(), piezo buzzer control

• Buzzer Beep SOS - Generates an audible SOS signal using a buzzer.

  Key Concepts: Sound patterns, timing with audio output

• Buzzer and LED - Synchronizes both LED and buzzer to create audiovisual feedback.

  Key Concepts: Multiple outputs, synchronization

• Buzzer Frequency Variation - Explores different frequencies and tones that can be generated with a buzzer.

  Key Concepts: Frequency control, tone() function with parameters

• Comparator Circuit - Compares two analog signals and produces a digital output based on the comparison.

  Key Concepts: analogRead(), conditional statements, analog-to-digital conversion Watch for Updates!

🎯 Getting Started

Installation

1. Clone this repository

git clone https://github.com/SBasu14/Basic-Arduino-Projects.git
cd Basic-Arduino-Projects/Programs 

2. Install Arduino IDE

• Download from the Arduino Official Website

• Follow the installation instructions for your operating system (Windows / macOS / Linux)

3. Connect Your Arduino

• Plug your Arduino board into your computer via USB

• Open the Arduino IDE

• Select the correct board and port:

• Go to Tools → Board → select your Arduino model (e.g., Arduino Uno)

• Go to Tools → Port → select the correct COM port

Uploading a Project

• Open the desired project folder
• Open the .ino file in Arduino IDE
• Verify the code (checkmark button) to check for errors
• Upload the code (arrow button) to your Arduino board
• Open Serial Monitor (if applicable) to view output
