Types of Arduino
There are sum types of Arduino Boards.
- Arduino Uno:
The Uno is a great choice for your first Arduino. It's got everything you need to get started, and nothing you don't. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a USB connection, a power jack, a reset button and more. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
- Arduino Mega:
The Arduino Mega is like the UNO's big brother. It has lots (54!) of digital input/output pins (14 can be used as PWM outputs), 16 analog inputs, a USB connection, a power jack, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The large number of pins make this board very handy for projects that require a bunch of digital inputs or outputs (like lots of LEDs or buttons)
- Arduino Leonardo:
The Leonardo is Arduino's first development board to use one microcontroller with built-in USB. This means that it can be cheaper and simpler. Also, because the board is handling USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more!
- Arduino Due:
It is a microcontroller board based on Atmel SAM3X8E, 32-Bit ARM microcontroller. It is developed by Arcuino.cc with the intention to provide an easy pathway for the beginners to get a hands-on experience with the module without any prior technical knowledge. You can just plug the device into the computer through a USB cable and start playing with it right away.
