If you are wondering if your Arduino product is authentic you can learn how to spot a counterfeit board here. Entry Level Get started with Arduino using Entry Level products: easy to use and ready to power your first creative projects. These boards and modules are the best to start learning and tinkering with electronics and coding. The StarterKit includes a book with 15 tutorials that will walk you through the basics up to complex projects.
We recommend that you have at least a decent understanding of these concepts before you dive in to the wonderful world of Arduino. Check out our Arduino Comparison Guide! We've compiled every Arduino development board we carry, so you can quickly compare them to find the perfect one for your needs. Take me there! The Arduino hardware and software was designed for artists, designers, hobbyists, hackers, newbies, and anyone interested in creating interactive objects or environments.
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. And that's really just the tip of the iceberg -- if you're curious about where to find more examples of Arduino projects in action, here are some good resources for Arduino-based projects to get your creative juices flowing:.
There are many varieties of Arduino boards explained on the next page that can be used for different purposes. Some boards look a bit different from the one below, but most Arduinos have the majority of these components in common:. Every Arduino board needs a way to be connected to a power source. The Arduino UNO can be powered from a USB cable coming from your computer or a wall power supply like this that is terminated in a barrel jack.
In the picture above the USB connection is labeled 1 and the barrel jack is labeled 2. The USB connection is also how you will load code onto your Arduino board. More on how to program with Arduino can be found in our Installing and Programming Arduino tutorial. The recommended voltage for most Arduino models is between 6 and 12 Volts. The pins on your Arduino are the places where you connect wires to construct a circuit probably in conjuction with a breadboard and some wire.
The Arduino has several different kinds of pins, each of which is labeled on the board and used for different functions. Just like the original Nintendo, the Arduino has a reset button Pushing it will temporarily connect the reset pin to ground and restart any code that is loaded on the Arduino.
Unlike the original Nintendo however, blowing on the Arduino doesn't usually fix any problems. This LED should light up whenever you plug your Arduino into a power source. Time to re-check your circuit! TX is short for transmit, RX is short for receive. These markings appear quite a bit in electronics to indicate the pins responsible for serial communication. The black thing with all the metal legs is an IC, or Integrated Circuit Think of it as the brains of our Arduino.
This can be important, as you may need to know the IC type along with your board type before loading up a new program from the Arduino software. This information can usually be found in writing on the top side of the IC. If you want to know more about the difference between various IC's, reading the datasheets is often a good idea. The voltage regulator 14 is not actually something you can or should interact with on the Arduino. The voltage regulator does exactly what it says -- it controls the amount of voltage that is let into the Arduino board.
Think of it as a kind of gatekeeper; it will turn away an extra voltage that might harm the circuit. Arduino makes several different boards, each with different capabilities. In addition, part of being open source hardware means that others can modify and produce derivatives of Arduino boards that provide even more form factors and functionality.
Here are a few options that are well-suited to someone new to the world of Arduino:. 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 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.
This is LilyPad Arduino main board! LilyPad is a wearable e-textile technology developed by Leah Buechley and cooperatively designed by Leah and SparkFun. Each LilyPad was creatively designed with large connecting pads and a flat back to allow them to be sewn into clothing with conductive thread. The LilyPad also has its own family of input, output, power, and sensor boards that are also built specifically for e-textiles.
They're even washable! At SparkFun we use many Arduinos and we're always looking for the simplest, most stable one. Each board is a bit different and no one board has everything we want -- so we decided to make our own version that combines all our favorite features. It'll work on Windows 8 without having to change your security settings we used signed drivers, unlike the UNO.
Just plug in the board, select "Arduino UNO" from the board menu and you're ready to upload code. The on-board power regulator can handle anything from 7 to 15VDC. It has lots 54! 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.
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! While your Arduino board sure is pretty, it can't do a whole lot on its own -- you've got to hook it up to something. There are lots of tutorials here on learn as well as the links back in the 'What does it do' section, but rarely do we talk about the general kinds of things you can easily hook into.
In this section we'll introduce basic sensors as well as Arduino shields , two of the most handy tools to use in bringing your projects to life. This board uses the Atmega microcontroller and Arduino bootloader in it. This board uses very less external component in it that makes the design easy and compatible.
The board requires 2 volt to 5 volt power supply and use large size pin holes so that it can be easily connect to other devices. This board is widely used for controlling different device that includes motor, light and switch.
The components of this board like sensor board, input board and output board can be washable because this board is used in clothing industries. This boards is considered as the microcontroller that uses the Atmega in it.
There are total 54 input pins and output pins in it in which 14 pins are of PWM output, 4 pins are of hardware port, 16 pins as analog inputs. There are additional pins that act as crystal oscillator having frequency of 16 MHz. The board also has flash memory of KB size that uses to store the data in it. As the board has large number of pins fitted in it that make the board suitable for projects that requires more number of pins in it. This board is considered as the microcontroller that uses the Atmega32u4 in it.
There are total 20 digital input pins and output pins in it, in that 7 pins are used As PWM and 12 pins used as analog inputs. There are additional pins which act as crystal oscillator of frequency 16 MHz. The microcontroller used by the Arduino Leonardo has in-built USB connection that removes the dependency of extra processor in it. As there is no additional USB connection in the board, it helps the board to act as mouse or keyboard for the computer system.
The Arduino Leonardo is considered as cheapest Arduino boards compare to other Arduino products. This board is compatible with Windows 8 operating system and there is no need to change the security settings to make this board working.
