5.4.2. Program

#include <LiquidCrystal.h>

#include <Servo.h>

// initialize the library of LCD RS,E,D4,D5,D6,D7

LiquidCrystal lcd(12, 11, 10, 9, 8, 7);

Servo myservo; // create servo object to control a servo

// a maximum of eight servo objects can be created

int pos = 0; // variable to store the servo position

void setup()

{

lcd.begin(16, 2);// initialize the LCD

myservo.attach(3); // connect servo at pin3

}

void loop()

{

for(pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees(step of one degree)

{

lcd.clear();

myservo.write(pos); // tell servo to go to position in variable 'pos'

lcd.print(pos);// display position on LCD

delay(15); // delay 15ms

}

for(pos = 180; pos>=1; pos-=1) // goes from 180 degrees to 0 degrees

{

lcd.clear();

myservo.write(pos); // tell servo to go to position in variable 'pos'

lcd.print(pos);// display position on LCD

delay(15); // delay 15ms

}
