How to choose the right Arduino online?
There are various versions of Arduino available, each having its own advantages and use cases; whether it’s in terms of shape, size, or the number of inputs and outputs. The three most commonly used Arduino versions are - Uno, Nano, and Mega.
If you’re a beginner trying to get into the world of Arduino, Uno is the most ideal option to go for. Arduino Uno is a microcontroller board based on the ATmega328P (datasheet). The entry price point isn’t too high but you still get ample ports for most projects in a relatively compact package. It has 14 digital pins and 6 analog pins, giving you a total of 20 GPIO pins available for your project.
The Arduino Nano is a small, complete, and breadboard-friendly board, based on ATmega328. It has the same functionality as the UNO, but with extra ports - 14 digital and 8 analog pins, as opposed to 6 analog pins in Uno. The board is about half the size of Uno and hence it’s ideal for use in applications where there is limited space.
If your project requires more than 20 GPIO pins, Arduino Mega might be your best bet. Arduino Mega is a microcontroller board based on the ATmega2560. It is a bigger version of Uno and comes with a lot of extra ports for versatility. It has 54 digital pins and 16 analog pins. With a total of 70 GPIO pins, it’s ideal for applications where you have a lot of peripherals and require extensive communications.
Some of the less commonly used boards are -
Arduino Micro is a microcontroller board based on the ATmega32U4, developed in conjunction with Adafruit. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, an ICSP header, and a reset button.
Pro Mini Board
Pro Mini 05 is a small microcontroller board compatible with arduino and is originally based on the ATmega168, intended for use on breadboards and when space is at a premium. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 8 analog inputs, and a 16 MHz crystal oscillator. It can be programmed with the USB Serial adapter or other USB or RS232 to TTL serial adapter.
Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU. It is the first Arduino board based on a 32-bit ARM core microcontroller. It has 54 digital input/output pins (of which 12 can be used as PWM outputs), 12 analog inputs, 4 UARTs (hardware serial ports), an 84 MHz clock, an USB OTG capable connection, 2 DAC (digital to analog), 2 TWI, a power jack, an SPI header, a JTAG header, a reset button and an erase button.
Leonardo R3 board
Leonardo R3 is a microcontroller board compatible with ATmega32u4. It has 20 digital input/output pins (of which 7 can be used as PWM outputs and 12 as analog inputs), a 16 MHz crystal oscillator, a micro USB connection, a power jack, an ICSP header, and a reset button.
LilyPad 328 ATmega328P
The LilyPad 328 Atmega328P mainboard is compatible with Arduino, (the low-power version of the ATmega168) or the ATmega328V. The LilyPad Arduino is designed for e-textiles and wearable projects. It can be sewn to fabric and similarly mounted power supplies, sensors, and actuators with conductive thread.
Arduino Pro (Retired)
The Arduino Pro is a microcontroller board based on the ATmega328. The Pro comes in both 3.3V/8MHz and 5V/16MHz versions. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs. The Arduino Pro is intended for semi-permanent installation in objects or exhibitions. The board comes without pre-mounted headers, allowing the use of various types of connectors or direct soldering of wires.
Why is Arduino a preferred choice, for beginners and experts alike?
Arduino is an open-source electronics prototyping platform based on flexible hardware and software, whereby the standard schematic can be used by anyone so as to make their own version of an Arduino board. Due to this reason, Arduino has a huge community behind the project - thereby also attracting beginners into the platform, especially when it comes to supporting and tutorials. You can check out our blogs for various arduino based projects.

Which Arduino board is best for beginners?
If you’re a beginner trying to get into the world of Arduino, Arduino Uno is the ideal option to go for. The entry price point isn’t too high and there are plenty of ‘Getting Started’ guides and project ideas available online.
It also comes with 14 digital pins - 6 capable of PWM output and 6 analog pins for a total of 20 GPIO Pins. It also supports I2C, SPI, and UART communication - giving you the flexibility to connect multiple of peripherals
Which Arduino board is best for Robotics?
If your robotics project requires a large number of digital and analog connections, Arduino Mega is a good option for small to medium-sized robots. In case your robot doesn’t require many ports, you can start off with Arduino Uno or Nano, depending on the board size constraints.
Which Arduino board is best for
#1. 3D printer
Arduino Mega is the most preferred Arduino board for building a 3D printer since it gives you a sufficient number of ports to work with a greater number of 3D printer accessories
Since space and weight is a huge factor when building quadcopters/drones, smaller versions of Arduino boards like the Nano or Pro mini are considered to be ideal.
#3. Embedded Systems
As embedded systems devices are usually made to integrate into a larger platform, smaller boards of Arduino like Nano and Pro Mini would be ideal for this application. For beginners, Uno provides a great start.
Almost any Arduino can be used for automation. Your requirement will only change based on the required number of GPIO pins. Mega and Nano are the most common choice for Automation based projects.
#5. Engineering Projects
Arduino Uno would be a great starting board for all sorts of engineering projects. In case more number of GPIO pins are required, you can always move onto the Mega
Arduino basics you should know before buying
How does Arduino work?
Arduino is an open-source electronics platform based on easy-to-use hardware and software. It is basically an AVR 8-bit microcontroller with some extra hardware, which includes - USB to serial for out-of-the-box programming, power management systems, 16 Mhz external crystal to make the AVR run faster and an expanded GPIO pin to easily connect sensors, devices, and peripherals. It works based on the set of instructions sent to the microcontroller.
How do I use Arduino?
Once you have the circuit for your project ready, connect the Arduino to your computer via a USB cable. Once plugged in, the onboard LEDs on the Arduino begin to flash.
Now your Arduino is ready to be ‘burned’. Arduino IDE is the official development environment for Arduino, and the programs are written in the C++ language. Once you’re done with the code, choose the appropriate port and board on the software, and upload the program to the Arduino.
Your Arduino must be running now.
Note: To help you get started, there are a number of example codes given under File -> Examples in the Arduino IDE, downloadable at the official Arduino website.

Are Arduino clones good?
Since Arduino is an open-source electronics platform, virtually any company can make an Arduino clone legally and sell it. The Arduino clones maintain compatibility with the official Arduino IDE software, used to program the microcontroller. Most Arduino clones cost significantly less due to cheaper components used to build the device. Therefore, reliability in the long term can be a potential issue, but as long as the boards aren’t used for mission-critical applications, an Arduino clone may be a good choice to save a few bucks.
