Which Arduino board is best for me?

Arduinos are the advanced form of microcontrollers that are easy to interface with different devices and capable of doing almost every assigned task. Since Arduino is a hardware and software-based platform, programming the microcontrollers has also been made easy using the Arduino IDE. The Arduino platform provides a large variety of boards having different specifications and one selects a specific board based on a task that is to be performed using the Arduino. To give a clear picture to the user which Arduino boards are best we have given a list of five Arduino boards.

Five best Arduino boards

The five Arduino boards that are discussed here are:

Arduino Uno for basic level projects

The Arduino board used for the beginner level projects is the Arduino Uno board as it is compatible with a variety of peripherals. This board is the most commonly used board as it is user friendly and easily configurable. Moreover, this board has an option of replacing its microcontroller which also makes it the first choice for the beginners. There are also a huge number of beginner level projects where this board can be used some of them are:

  • Temperature controlled fan
  • Visitor counter
  • Obstacle detection
  • Home security system

The specification of the Arduino Uno board are given in the table given below:

Specifications Arduino Uno
Microcontroller ATmega328P
Digital pins 14
Analog pins 6
Pins for pulse width modulation 6
Static RAM 2KB
Flash memory 32KB
EEPROM 1KB
Operating voltage 5 volts

Arduino Nano for breadboard projects

From the name it can be assumed that this board will be of smaller size and will perform a limited number of functions as compared to the other Arduino boards. However, despite having smaller size it can be used in number of projects some are given below:

  • Plants watering system
  • Using LED for indications
  • Monitoring the water level
  • Interfacing DC motors
  • Taking inputs using keypads

Due to its small size this board is suitable for the projects that use breadboard as it has built-in header pins so that it can be fixed on breadboard and for beginner’s level students it is a best option. This board does not have any power jack for power supply, so it relies only on its used port for power supply, or the external power supply given through the breadboard.

The technical specifications of the Arduino nano is given in the table below:

Specifications Arduino Nano
Microcontroller Atmega328
Digital pins 14
Analog pins 8
Pins for Pulse width modulation 6
Static RAM 2KB
EEPROM 1KB
Flash memory 32KB
Operating voltage 5 to 12 Volts

Arduino Mega 2560 for advanced level projects

The Arduino Mega is suitable for complex and advanced level projects as it comes with a large number of input output pins. Unlike the Arduino Uno and Nano, the Arduino Mega has higher RAM, higher memory and a faster microcontroller. There are wide range of projects in which the Arduino Mega 2560 can be used some of them are:

  • Food quality prediction
  • Creating a bioprinter
  • Robotic arm based on gesture control
  • Seismic activity monitor

The specification of the Arduino Mega is given in the table below:

Specifications Arduino mega 2560 Rev3
Microcontroller ATmega 2560
Digital pins 39
Pins for pulse width modulation 15
Analog pins 16
Static RAM 8KB
Flash memory 256KB
EEPROM 4KB
Operating voltage 5 volts

Arduino Due for big and complex projects

The Arduino Due is a viable option when it comes to big projects having large codes because it is equipped with a 32-bit ARM core microcontroller and a memory of 512 kilobytes. Moreover, it has a dedicated port for 9 volts battery power when the board is to be required to run at independent mode. Furthermore, the controller used in this board is faster as compared to all other Arduino boards. There are variety of projects which uses the Arduino Due board some of them are:

  • Interfacing the TFT displays
  • Making a quadcopter using Arduino Due
  • Arbitrary waveform generator
  • Make a small computer using Arduino Due

The technical speciation of Arduino due are given in the table displayed below:

Specifications Arduino Due
Microcontroller Atmel AT91SAM3X8E ARM Cortex
Analog pins 12
Digital pins 54
Pins for pulse width modulation 12
Static RAM 96 KB
Flash memory 512KB
Operating voltage 3.3 to 12 volts

Arduino MKRZero for Audio and sound projects

The Arduino MKRZero is used in the projects which are totally related to the audio or is a viable option for the music makers. This board comes with header pins which makes it easy to interface it with the devices using a breadboard. There are number of audio projects that require the use of Arduino MKRZero board some of them are:

  • Generating the melodies
  • Activating LCD using sound sensor
  • Mini piano
  • Band audio spectrum

For technical specification a table of the specification of the Arduino MKR zero is given below:

Conclusion

The Arduino platform provides a large number of boards each having different features and specifications. Therefore, selecting any one of them is kind of a difficult task but we can divide the boards based on the type of projects we want to do. For basic level projects mostly, the Arduino Uno is used and for advanced level projects the Arduino Mega and Due boards are used. Furthermore, for the projects which include sounds or music as their input or output the Arduino MKRZero is recommended.
