Prezentare "frumoasa" sketch/program in articol (II)

   In precedentul articol am prezentat cum afisez frumos un cod/program/sketch, apoi cum fac un text de dimensiuni mari sa fie afisat intr-o fereastra mica.
   Deoarece nu vreau sa instalez programe si alte "ajutoare", am mai cautat si am ajuns la concluzia ca am cautat prea departe, in sensul ca inclusiv programul Arduino IDE are facilitatea de a copia codul si a-l transforma in cod HTML, sketch-ul aratand intuitiuv (cu anumite culori, de exemplu):

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.
 */
 
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;

// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);     
}

// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);               // wait for a second
}

   Acest tip de prezentare nu elimina problema textelor lungi, asa ca e vreu ceva de genul:
