Arduino, Open Source?
Arduino boards are pint-size circuit boards used to enhance hardware and software to projects. Arduino, demarcated by the originators, is an open-source microchip technology prototyping podium based on malleable, easy-to-use hardware and software and language. However, open-source funds the programming and board alignment is spontaneously available for circulation and modification. This means there are deviations of the board obtainable, reaching from gaming explicit to education.
These boards are all seated in the open source roots. There are different types of official boards and dozens more variety and kits available in the industry. On the other hand, the differences between each board may seem unnerving. But focus should remain on the project or goal in mind. The remain of the article will discus each board important terms to help narrow down that is perfect for the sketch project in hand.
Talk About Arduino Uno!
The informal standard board is Arduino Uno. It is paramount choice for the beginners. This board has a ATmega328 processor with 8 bit CPU (Central Processing Unit), and clock speed set as 16 MHz quartz crystal, 2 KB SRAM and finally 32 KB of flash storage.On the other hand, supplementary features include 14 digital input/output pins with 6 analog input pins. Also, a removable micro controller. The power-up voltage range is 7 to 12 Volts and USB connection to upload the instruction given by the PC/Mac.
The Arduino LEONARDO is an combined USB HID board where superlative for projects demanding the board to perform as a USB human interface devices. This board has a ATmega32U4 processor with 8-bit CPU, 16 MHz crystal oscillator and operate on 5V of power supply. It has 20 digital input/output pins which 7 can be used as for power outputs and 12 as analog inputs.
The Leonardo differs from all preceding boards in that the ATmega32u4 has build-in USB communication, eliminating the need for a secondary processor. This implies that the Leonardo connected to computer, work as plug and play device like a mouse or a keypad.
What is Breathtaking Feature on Arduino 101
The Arduino 101 is recognized as ease of use of the classic board with latest technologies. This board comes with 14 digital input/output pins which 4 can be used as PWM outputs pins, 6 analog input pins, a USB connector for serial communication and sketch upload, a power jack and ICSP header with SPI singles and l2C dedicated pins. The operating voltage and I/O is 3.3V and all pins are protected against 5V over-voltage.
The Breathtaking feature is with the processor; where module contains two tiny cores, an x86 Quark with a 32-bit ARC architecture core where both clocked up to 32 MHz. The Awesome feature is with addition of on-board Bluetooth capabilities and a 6-axis accelerometer/gyro where you can explore your brain with new creativity and spread your creative wings to the world.
The Duemilanove or Arduino Due which is named for the same Arduino boards which are the newest among board collection. The Due board has an Atmel SAM3X8E Cortexx-M3 (AT91SAM3X8E) processor with 32-bit CPU and 512 KB flash storage, 84 MHz clock speed with 96 KB SRAM. This has additional features including 54 digital input/output pins among 12 pins allocated for analog input plus 2 pin support for analog output with native USB support. The form factor is at 2.4 inches by 2.1 inches where similar to the Uno and Leonardo. Arduino Due is the first 32-bit ARM core microcontroller.
Keep in mind that unlike most of other Arduino boards, the Due board power supply at 3.3V; This figure apply to all I/O pins which maximum voltage can tolerate is 3.3V. Applying more than higher voltages to any I/O pins could be damage to the Arduino Due board.
Tiny Arduino Micro!!
The smallest board of the family of Arduino is Micro, which inherited by Arduino Leonardo with two more analog inputs. This board based on the ATmega32U4 processor with 8-bit CPU, developed in co-occurrence with Adafruit. It works under 7-12V power supply and 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. In addition 2.5 KB SRAM and 512 KB flash storage with 16 MHz clock speed give more power to the board for greater creation to the world. Arduino Micro can be use for any projects that limit with the size and the weight; where form factor is very low as 1.9 inches by 0.7 inches.
Like A Flower, LilyPad Arduino!
The LilyPad board abjures old-fashioned board form factor for a 2-inch diameter disc. The processor is an ATmega328 through 8-bit CPU, 16 MHz clock speed, 2 KB SRAM, and 32 KB flash loading. Bonus features include 14 digital input/output pins and 6 analog input pins. The hardware is just about indistinguishable to the Arduino Uno, with numerous possibilities counting USB, unpretentious, and meek Impulsive.
Featured Arduino ESPLORA
It fluctuates from entirely preceding Arduino boards in that it affords a figure of built-in, ready-to-use set of on-board sensors for communication. It’s deliberate for society who want to become and execute with Arduino deprived of consuming to study about the microchip technology foremost. On the other hand, comparable the Leonardo board, the Esplora habit an ATmega32U4 AVR micro-controller through 16 MHz crystal oscillator and a micro USB assembly accomplished of performing as a USB consumer device, identically a mouse or a keyboard.
The Esplora has commit sound and light outputs, and numerous input sensors, together with a slider, a socket for a color TFT LCD screen, a joystick, a temperature sensor, an accelerator, a microphone, and a light sensor. It also has the latent to enlarge its competences with two Fiddle kit input and output connectors .
More over, the Arduino YUN is a dedicate disparity on the Leonardo board. It grips cloud-based connectivity using a separate on-board Linux classification. The processor is an ATmega32U4 with 8-bit CPU, 16 MHz clock speed, 2.5 KB SRAM, and 32 KB flash packing. Certainly, features embrace 15 digital input/output pins, 12 analog pins, and instinctive USB sustenance. The form factor is four-sided, determining the identical as the Uno and the Leonardo.
