4.1. To blink a LED

blink a LED
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn LED on (HIGH is the voltage level)
delay(1000); // wait for 1000ms = 1 second
digitalWrite(LED_BUILTIN, LOW); // turn LED off by making the voltage LOW
delay(1000); // wait for a second
}

4.2. To print message(Hello World!) on the screen

#include <Wire.h>
#include "rgb_lcd.h"

rgb_lcd lcd;
const int colorR = 255;
const int colorG = 255;
const int colorB = 0;

void setup() {
  digitalWrite(38, HIGH);
   Serial.begin(9600);

   lcd.begin(16, 2);
  lcd.setRGB(colorR, colorG, colorB);

    // Print a message to the LCD.
  lcd.print("Hello world!");
  //delay(1000);
}

4.3. To show result of supersonic range finder on the screen

#include "Ultrasonic.h"
#include <Wire.h>
#include "rgb_lcd.h"

rgb_lcd lcd;
Ultrasonic ultrasonic(7);

void setup()
{
 digitalWrite(38, HIGH);
 lcd.begin(16, 2);
 Serial.begin(9600);
  lcd.print("The distance is: ");
}
void loop()
{
 long RangeInInches;
 long RangeInCentimeters;

 Serial.println("The distance to obstacles in front is: ");
 RangeInInches = ultrasonic.MeasureInInches();
 Serial.print(RangeInInches);//0~157 inches
 Serial.println(" inch");
  lcd.print(RangeInInches);
  lcd.println(" inch");
 delay(250);

 RangeInCentimeters = ultrasonic.MeasureInCentimeters(); // two measurements should keep an interval
 Serial.print(RangeInCentimeters);//0~400cm
 Serial.println(" cm");
 lcd.print(RangeInCentimeters);
  lcd.println(" cm");
 delay(250);
}
