Theory, hardware, software and code
In this article we will present one possible method to put a bootloader into a virgin Arduino's ATMega 328P.
We'll utilize :

You have an Arduino board and you bought a new ATMega328 microcontroller for new projects; after mounted it onto the board you discovered it doesn't work.
Why this?
In picture beside we can see something interesting: "avrdude" and specially "not in sync"; simply it's impossible to communicate or send datas to ATMega: it's not ready!
"Ready? what does it mean"!?
Think you have a baby: he's not ready to take care of himself, but you are, both for him and for you!
Same with microcontroller: control it by external hardware (adult to baby), or give it (baby) the way to become independent.
We're covering this second aspect, that needs a little piece of code.
Sensoristic applying field is fascinating, and sometimes sounds magic or something common people cannot approach immediately.
Our body is full of sensors (like ears) able to capture vibrations or other stuff: so you natively have parameters which to confront and start with.

Breadboard is an important tool for electronic circuits prototyping, it gives you possibility to easily interconnect and test components you need before any other superior step like translating everything directly on a copper clad circuit/laminate board; and it's reusable for a long time.
Arduino is one of the most famous microcontroller board.
Trying to explain what exactly it is shows multiple difficulties that progressively fade away with practice.
Maybe one feature could intrigue above all others: programming language is a high level one!
