3D, Money and Power - Independent Research Regarding Computer and Human Interaction

Dear Sirs,

It was about two years ago that I decided to re conciliate with what I usually call mekhane, or machine, starting to approach and study once again in my life the state of the art regarding computer networks, human and machine interactuation and related aspects in present running days.

My first inscription quote was acquiring an AMD desktop unit pret-a-porter, machine I got to buy in a mainstream electro domestics company -with windows preinstalled also thus prepaid-, from where I am typing these actual lines and that has accomplished wonderfull tasks during my study development.

Second investment on my personal education was another improved middle class gaming machine, also from AMD manufacturer, this time delivered from Madrid from a well unowned internet computer online store, with a really nice Free and Open-source -up to my scarce understanding- Debian desktop GNU/Linux distribution that I personally installed.

Both really smooth, and for my expectations at this time -I maintain as a hobby some cryptocoin mining activity- it is doing an amazing work. I am very happy with its performance and under some requirements both can be used for different tasks for common goals. I have also invested in Arduino boards multiple sensors and actuators, relays and also a raspberry pi, all of which of most value in the so called Internet of Things experimentation field.

As you may understand I am a self-made studier, that is I did not have a teacher but many during my life, all people whom I respect and that formed part of my life experience for long and short periods of time. I also or neither never had a very much defined study object -a program I could say-, but the will to learn new things and feel alive, the enthusiasm for learning.

I feel now as if the initial work is done, but when I interact with one, many or some of the aspects I once hand-printed in paper so to make up my mind, the whole puzzle changes and it makes me feel I get a small clue of what one is all and all is one means. This is unfinished work, and it is and will be licenced with Creative Commons v 4.0 International Atribution. So I just decided to publish this paper, in case anybody would like to have a say regarding this interesting fields, please feel free to contact me in most suitable way.

Sincerely yours,

Luis Rodriguez

Arduino smart light response system - Basic concepts

Easy and impressive as usual, Arduino boards allow any ignorant such as me myself and I to develop a unique and relatively cheap controller capable of reading the light state surrounding a given sensor and translate it to some command, hereby light a brand new second hand led -that is on or off according to environmental needs-. Simple, fast and closed circuit. Adding a relay is just a matter of time isn't it?

Want to see it in action?. Check out this video of the gadget at work:


Here is the code that runs it. No more, no less:

// Led on only when the light is out.


int photoRPin = 0; 
int lightLevel;
int LEDpin = 13;


void setup() 
{
 Serial.begin(9600);
}

void loop()
{
 lightLevel=analogRead(photoRPin);

 Serial.println(lightLevel);{       
   
 if(lightLevel > 526)
 {
   digitalWrite(13, HIGH);

 }
 else if(lightLevel <= 526){
 digitalWrite(13, LOW);
 }


 delay(250);

}
}
