Arduino is an open-source single board microcontroller with easy-to-use hardware and software. It’s made for the artists, designers, hobbyists and all fun loving electronics enthusiasts that love to build small interactive projects that can be used in our daily life. The microcontroller on the board is programmed using the Arduino programming language and the Arduino development environment. Arduino projects can be stand-alone or they can communicate with software running on your computer.


The Arduino programming language is pretty simple to learn.  The code you write for your Arduino are known as sketches. They are essentially in C++. The code itself is easy to understand. The code below shows how self explanatory the code for blinking an LED is.


#define LED_PIN 13
void setup () 
 pinMode (LED_PIN, OUTPUT); }
void loop () 
 digitalWrite (LED_PIN, HIGH); 
 delay (1000); 
 digitalWrite (LED_PIN, LOW); 
 delay (1000); 

The biggest strength of the Arduino Community are the users who develop Arduino projects, share ideas and code to the Arduino projects, guide beginners by answering questions and helping out at the forums and also provide invaluable feedback. The online community has people from all over the globe come and share their thoughts. They also have region specific and special interest groups.

A USB cable powers the device. Arduinos can run standalone by using a power supply as well. Once you’ve burned the program into the board, you can opt to give it an external power supply. But this is entirely dependant on what you’re using it for and circumstances you want to use the device in.


You can build your own Arduino board or it can be purchased pre-assembled; the software can be downloaded for free.

Just in case you’d like a little inspiration to start, here are a few Amazing Arduino Projects.
