#1 What is Arduino ?

🎉🎊 We Are Revamping! Finally! 🎊🎉

 After getting so much support and love from you guys ❤️, 

I decided to start a new blog. 

We are migrating from Blogspot to a WordPress based personal website/blog!

  

So this blog will be archived from now onwards and will no longer be updated.

For all the new blog posts & exciting things bookmark my new blog/website.

!! These are the new links !!

Blog/Website:- https://www.thevirajshelke.com

Facebook:- https://www.facebook.com/thevirajshelkeblog

Hoping for lots of support and love from you all ❤️

Stay Tuned 😉

This is 1st post on Arduino tutorial.

What is a Microprocessor / Micro-controller ?

• Processor is something which processes a data and provides us a desired output.
• Processor accepts one or more inputs, operates on them and provides us with desired output [Input is never equal to output, if it has to be then there is no processing done].
• Digital Electronics operates on two levels[High & Low] and we have many different digital circuits, logical gates etc. for processing data.
• Soon technology developed, we had Integrated circuits & whole digital world started to shrink.
• We now had the circuit which could process data on a Micro-chip & from here came Microprocessors.
• Microprocessors can be programmed according to the required application. 
• Microprocessors are found everywhere like phones, cars, computers & this list continues.On an average a common man comes across 68 microprocessors a day !
• And the funny thing is 98% of  total Microprocessors lie outside computers ! :-P
• Micro-controller is a microprocessor to which we have attached external components. [visit the link for more details].

What is Arduino ?

• Microprocessor requires many things for its working like a crystal, capacitors etc. & then we have circuit to which we can attach our input & output devices.
• Now few people thought of making a circuit board [referred to as Development board] which had everything that is required for a Microprocessor to work!
• Arduino was one such company that came up with a development board named Arduino & their own IDE to program the microprocessor on it.

Why Arduino ?

• We can develop our own board too, but since arduino does a good job we can have our project's little work done. Arduino has real wide range of Boards with many different processors on it, having different specifications. 
• And basically the IDE made by arduino uses basics of C-programming & java to write programs, which are then compiled and burned [Written] on the chip. [Otherwise we need to write programs in Embedded C or Assembly Language & burn on chip].
• So using Arduino not only helps us in hardware point of view but also our programming becomes very easy!

List of Arduino Boards is here.

For beginners it's advisable to start off with a basic board like Arduino UNO.

Even I had started with this & believe me it's pretty easy.

Once you learn using one development board you can really work on rest of them easily & by yourself.

Note :- Now this page might seem little way to easy for someone reading it, but one who wishes to learn Arduino must have a basic knowledge about Microprocessor, Microcontroller & Programming.

 [Obviously more then what I have mentioned :-P].
