Working with Arduino

Intro
Arduino is an open source hardware and software.
The software is used to transit code to the memory of the connected machine.
It provides a user friendly environment to type C code: this is possible because it doesn’t show all the processes going on in the machine.
This aspect could be really helpful for beginners but it could turn turn into an obstacle :((.

“Music is made of the same medium as speech”- reflection on vocabulary
Connections between sound vocabulary and speech vocabulary. Technical sound vocabulary has often a correspondence in terms used to describe our way to communicate.
Some examples:
- pitch 1.[sound]quality that makes it possible to judge sounds as "higher" and "lower" ; 2. [as a verb] move or be moved suddenly, especially by throwing or being thrown; 3. [noun(persuasion)]a speech or act that attempts to persuade someone to buy or do something (es, elevator pitch discourse); 4. [noun] the level of a feeling;
- juxtaposition 1. [noun]the fact of putting things that are not similar next to each other; 2. [literary] is the showing contrast by concepts placed side by side. Example: "Ask not what your country can do for you; ask what you can do for your country" J.F. Kennedy 3. [sound] an abrupt change of elements, a procedure for musical contrast like rhythmic, melodic and harmonic contrast.

Functions *work in progress
To convert images into HEX ( *and make a sort of animation):
1. I prepared a simple black and white image using illustrator\photoshop. I exported it as a bitmap file with a resolution compatible with the one used by the TV OUT mode (128x96px). 2. I used an online tool to convert the image into hexadecimal code. Not all of the options found in the internet are able to create an array compatible with the arduino code. These are the ones that worked better for me:
- https://tomeko.net/online_tools/file_to_hex.php?lang=en (It works with images of a 128x96 px size that means all the screen in the TVout mode. I don’t know why but when It creates the code it flips the image vertically [*!?] so I flipped it before doing the convertion;
- http://marlinfw.org/tools/u8glib/converter.html (It works also with smaller images, even in a jpg or png format).
3. I added in my Arduino code folder two file extensions (.cpp & .h) copied from the DEMOPAL example. Then I replaced the code of the previous image with the one that I generated with the converter tool: (.cpp file):
- include “filename”
const unsigned char filename [] PROGMEM = { 128,96, // image size
- hex code*
}; (.h file):
- include <avr/pgmspace.h>
- define FILENAME_H
extern const unsigned char filename [];
