Arduino Types

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.



What is Arduino Board

What is Arduino Board

Introduction:

                         Arduino is an open-source platform used for building electronics projects. Arduino consists of both a physical programmable circuit board (often referred to as a microcontroller) and a piece of software, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.
The Arduino platform has become quite popular with people just starting out with electronics, and for good reason. Unlike most previous programmable circuit boards, the Arduino does not need a separate piece of hardware (called a programmer) in order to load new code onto the board -- you can simply use a USB cable. Additionally, the Arduino IDE uses a simplified version of C++, making it easier to learn to program. Finally, Arduino provides a standard form factor that breaks out the functions of the micro-controller into a more accessible package.



What Does it Do?

The Arduino hardware and software was designed for artists, designers, hobbyists, hackers, newbies, and anyone interested in creating interactive objects or environments. Arduino can interact with buttons, LEDs, motors, speakers, GPS units, cameras, the internet, and even your smart-phone or your TV! This flexibility combined with the fact that the Arduino software is free, the hardware boards are pretty cheap, and both the software and hardware are easy to learn has led to a large community of users who have contributed code and released instructions for a huge variety of Arduino-based projects.
For everything from robots and a heating pad hand warming blanket to honest fortune-telling machines, and even a Dungeons and Dragons dice-throwing gauntlet, the Arduino can be used as the brains behind almost any electronics project.

Following up on the success of cochlear and retinal prostheses, neuroscientists see a limitless horizon for related devices that will read electrical and chemical signals from the nervous system to improve quality of life for people suffering from injury or disease.


Such devices, neural prosthetics, will help a wide range of people, including people with epilepsy, wounded war veterans suffering post-traumatic stress disorder and traumatic brain injury, people with treatment-resistant depression and chronic pain, victims of Alzheimer's disease, people with speech disabilities, and individuals who have sustained spinal cord injury and loss of limbs.
But before neural prosthetics can advance, engineers will need to design and fabricate devices that can survive in the harsh environment of the human body, without causing tissue infection and other serious adverse conditions. In addition to enhancing materials performance, researchers are developing interface technologies that enable micro-devices to safely reside in human tissue for long time periods.
Researchers at the U.S. Department of Energy's Lawrence Livermore National Laboratory (LLNL) are making gains with thin-film flexible-polymer materials. In experiments with auditory prosthetics, neural interface micro-electrodes are embedded in polymer, allowing the device to move naturally and conform to live tissue. The polymer materials have mechanical properties that more closely mimic neural tissue than the micro wires used in current cochlear and deep-brain-stimulating implants.
"Among the engineering challenges associated with neural prosthetics is the biocompatibility of the implant," said Sarah Felix, a lead research engineer at LLNL and also a member of ASME. "Research suggests that polymer is more compatible with the human body than the silicon in conventional neural probes used in neuroscience studies."
Toward reliability
Researchers believe conventional, rigid, neural devices cause micro tearing in human tissue because neural tissue is softer than the device. According to Felix, the flexibility of a thin-film polymer probe mitigates this problem. However, the flexibility also makes polymer devices difficult to implant. Felix's solution is to temporarily attach a rigid stiffener.
"For the polymer neural interfaces, we attach the device to a needle-like stiffener using bio-dissolvable polyethylene glycol (PEG) to enable extraction of the stiffener after surgical insertion," said Felix. "An innovative bonding process enables accurate alignment of the device to the stiffener."
A novel feature of the design is a shallow channel running lengthwise, which allows the even distribution of the PEG, or other bio-adhesive, during assembly and implantation. Felix's team used the method to implant unique, dual-sided, polymer electrode arrays into brain tissue, and these arrays successfully recorded neural signals.
A promising future
The LLNL researchers believe their devices and surgical methods can also apply to future applications in deep-brain- and spinal-cord-stimulation, which will enable physicians to advance neural prosthetics to the next level of human health and rehabilitation. In fact, LLNL is currently developing neural implants that will restore auditory, motor and bladder function; aid speech; and control depression and epilepsy.
Each year, the U.S. National Institutes of Health (NIH) spends $6.5 million on neural prosthetics research and development, and today several of the most prestigious medical-research institutions in the United States — Case Western University and the Massachusetts Institute of Technology among them — are engaged in promising clinical studies.
Many medical scientists believe the sky is the limit for neural prosthetics, but ultimately it is the engineering community that will need to design and fabricate devices that enable the realization of the promise of neural modulation for patients. [Eternal Sunshine of the Bionic Mind: Prosthesis Could Restore Memory]
Said Felix: "There exist many engineering considerations with neural prosthetics, particularly in the interface of the device with human tissue. Engineers must think about a complete range of issues, from electrode materials and the lifetime of the implant to electronics and signal processing. This will be an intriguing pathway of multidisciplinary scientific and engineering development for many years to come."
