But first, let‘s quickly cover what makes Arduino boards so special…

What Are Arduino Boards and Why Are They So Popular?

An Arduino board contains an Atmel microcontroller chip functioning as the "brains" of the operation. The chip handles processing duties, executing code instructions, and controlling connected components.

Surrounding the chip, you‘ll find:

• Input/output pins – Connect sensors, lights, motors, buttons, speakers and more to these pins
• USB port – Provides power and a connection to your computer
• Power jack – Plug in batteries or a power adapter to run your board in standalone mode
• Reset button – To reboot your board when needed

Here‘s a close-up example of an classic Arduino Uno board so you can see these key components:

Unlike low-level microcontrollers, Arduino boards are designed specifically to make it easier for novices to get started. Thepre-burned bootloader allows uploading code wirelessly without requiring additional hardware. The simplified programming language based on C++ streamlines writing your first Sketch (Arduino software programs).

Abundant tutorials, forums, libraries, and code examples from the Arduino community lower barriers for complete beginners. Yet advanced coders can still leverage boards in sophisticated applications. This combination of accessibility and open-ended versatility is why Arduino became the most popular electronics platform.

Now let‘s dig into the distinct models available! We‘ll categorize boards into "Entry-Level" for first-timers vs. "Enhanced" with advanced capabilities.

I‘ll highlight strengths of each, example projects, key specs in neat comparison tables, images, and expert recommendations on ideal use cases. Just what a geeky guide should provide! You‘ll be well-equipped to decide which Arduino board is the perfect match. Let‘s get started!

Entry-Level Arduino Boards – Great for Beginners

I always recommend starting out with economical but surprisingly capable entry-level Arduino boards. They utilize 8-bit controllers, run at lower speeds, and have limited connectivity. But don‘t let that fool you – they can still control LED displays, gather sensor data, even operate small robots!

And with abundant tutorials and sample projects, new makers can quickly get up-and-running. Here are my top picks:

Arduino Uno (R3) – The Classic Board to Start With

If I could only choose one, the Arduino Uno is hands-down my top recommendation as an entry point, especially for complete newbies.

As the most popular model ever manufactured, countless resources exist to walk through getting started, programming help, add-on libraries, and pre-made Sketches to load onto the board. I built my first bipolar "mood light" prototype that syncs its color to stock market prices in 30 minutes!

It strikes the perfect balance of affordability and capability. Key specs:

• Microcontroller: ATmega328P
• Digital I/O Pins: 14 (6 provide PWM output)
• Analog Input Pins: 6
• Clock Speed: 16 MHz
• USB, power jack
• Wide array of plug-and-play shields to simplify adding capabilities

I especially appreciate the over 1,000 existing Arduino shields that stack onto the Uno extending features – think motor drivers, WiFi connectivity, touchscreen LCDs, global positioning sensors… endlessness creativity!

The Uno empowers beginners to quickly build LED grids, simple robots, sensor prototypes. Down the road, it still handles more advanced fare like home automation systems and Internet-of-Things devices. Tremendous value!

Arduino Nano – Tiny Package, Lots of Potential!

The Arduino Nano packs the capabilities of an Uno into a pleasing petite package just 1-inch x 1.5-inches. I call it the "Mighty Mini Me" version. The shrunken size comes from replacing bulky USB ports with a narrower mini-USB connector.

Don‘t need something super small? The Uno above may be easier for initial projects. Otherwise, the Nano is fabulous for squeezing into places bigger boards can‘t fit – like robots, handheld gadgets, and wearables. Check the specs:

• Microcontroller: ATmega328P
• Digital I/O Pins: 14
• Analog Input Pins: 8
• Clock Speed: 16 MHz
• Mini USB connection

You‘ll need a FTDI connector to link the Nano to your computer vs. direct USB cables with the Uno. A solvable minor hassle.

Example fun projects are mini robots, VR hand controllers, embedding inside 3D printed creations, and interactive jewelry! Anything needing a covert compact controller.

Arduino Micro – Small Yet Mighty

Last "entry-level" pick, I swear! But the Arduino Micro deserves a mention because it crams heightened capabilities into an even smaller footprint than the Nano. Truly tiny but mighty!

Dimensions are just 2.7-inches x 1.9-inches with on-board USB directly soldered on. The shrunk size does lower overall digital/analog pins to 20 and 12 respectively. Downside of less connectivity is balanced by the highly portable format great for transportation projects.

• Microcontroller: ATmega32U4
• Digital I/O Pins: 20
• Analog Input Pins: 12
• Clock Speed: 16 MHz
• On-board USB

You could build a miniature GPS tracker to monitor a pet‘s location. Or embed as the controller inside robot insects… sky‘s the limit!

I‘ll summarize key specs of these entry-level boards in this handy comparison chart:

As you can see, any would be an excellent starting point. But most support the Uno – tough to beat for beginners!

Enhanced Feature Boards – Take Your Projects to the Next Level

Once you‘ve exhausted the entry-tier board capabilities, it may be time to step up your game!

These enhanced Arduino boards tout more advanced 8 or 32-bit microcontroller chips, faster speeds, capacious memory, wireless connectivity, endless I/O pins… They open the gateway for robotics, automation systems, machine learning classification, computer vision experiments, and bleeding-edge IoT devices.

Let‘s check out top "pro-level" boards I recommend once Arduino fever takes hold!

Arduino Mega (R3) – Massively Expandable Powerhouse

When your projects demand some real horsepower, I suggest the aptly named Arduino Mega 2560 R3 model – essentially a "super-charged" version of the Uno.

You‘ll immediately notice the bigger physical footprint hints at expanded capacity inside to effortlessly crunch data from gobs of inputs and drive extensive outputs simultaneously.

We‘re talking a 8-bit ATmega2560 chip at 16MHz speed – very respectable. But the eye-catching specs are tremendous headroom for add-ons:

• Digital I/O Pins: 54
• Analog Inputs: 16
• PWM Outputs: 15

Numbers don‘t lie! You can prod, sense, and actuate three times more components compared to an entry-level board like the Uno.

I recently witnessed a brilliant eleven-year-old (totally jealous) leverage the Mega to animate a doll using two dozen servos, speech synthesis for vocals, facial recognition triggering reactions, even text-to-speech conversations – so incredibly cool!

Yet with abundant guides and near-identical coding style to basic models, new Makers shouldn‘t fear the Mega. Leverage it‘s beefy brawn once you outgrow lower-tier boards!

Arduino Due – Welcome to 32-bit Processing Power!

Who says Arduino projects must remain simplistic? The formidable Arduino Due board breaks ties by adopting a 32-bit ARM Cortex-M3 chip running at a lightning-fast 84 MHz clock speed!

We can achieve near Raspberry Pi-levels of number crunching to conquer computationally-intensive duties like computer vision, neural networks, filters, voice recognition, servo control, and more with gusto.

Critically, tremendously fast response times under 10 microseconds when gathering analog sensor inputs empowers the Due for applications requiring real-time reactions.

Befitting advanced capabilities, connectivity and memory matches with:

• 12 analog inputs, 54 digital I/O pins
• 12 PWM outputs
• 96 KB RAM, 512 KB flash storage

Before purchasing, be aware the Due CANNOT leverage classic Arduino shields, runs at 3.3V logic levels, and costs more around $38. Yet for sequel projects hungrier for computing horsepower, it‘s a beast in compact form factor!

LilyPad Arduino – Wearables Get a High-Tech Upgrade

Let‘s shift gears to a completely unique Arduino species purpose-built for powering today‘s wearable electronics revolution – the ingenious LilyPad!
