  • Arduino comes in many shapes and sizes! While the Arduino Uno is the most beginner-friendly board, there are many other versions made for different kinds of projects — from wearable tech to powerful robots.

    • 🧩 Why So Many Models?

      Each Arduino model is designed for a specific purpose — some are smaller, some have more memory, and others can connect to the internet or Bluetooth. Let’s take a look at some popular ones:

      📊 Comparison Table: Popular Arduino Models

      Arduino Model Main Features Best For Size
      Arduino Uno Standard board, 14 digital pins, 6 analog inputs Beginners, general projects Medium
      Arduino Nano Compact size, breadboard-friendly, USB-C option Space-limited projects Small
      Arduino Mega More pins and memory, 54 digital I/O pins Large robots, 3D printers Large
      Arduino Leonardo Acts like a keyboard or mouse, USB built-in HID projects (e.g., custom keyboards) Medium
      Arduino MKR WiFi 1010 Built-in WiFi and Bluetooth IoT (Internet of Things) projects Small-Medium
      Lilypad Arduino Washable, made for sewing into clothes Wearable electronics Very Small

      📦 Fun Fact!

      The Lilypad was one of the first Arduinos designed specifically for wearable technology — you can sew it into jackets or bags and make them glow, beep, or react to movement!

    • 🎓 What to Choose?

      As a beginner, it’s best to start with the Arduino Uno. But as you grow, you’ll love exploring others depending on the project. Bigger robot? Try a Mega. Want to build a smart home device? MKR WiFi 1010 could be your pick!
