Exercise 6

Create a program to sweep the servo back and forth between 0^o and 180^o gradually such that it takes a total of 18 seconds to complete a back and forth sweep

Hint :

Increment and decrement by 1^o, with a 50 milliseconds delay at each step

Solution

#include <Servo.h> 
 
Servo myservo; 
int pos = 0;    
// variable to store the servo position 

void setup() 
{ 
  myservo.attach(7);  
} 

void loop() 
{ 
  for(pos = 0; pos <= 180; pos++)
  {                                
    myservo.write(pos);            
    delay(50);                     
  } 
  for(pos = 180; pos >= 0; pos--)   
  {                                
    myservo.write(pos);            
    delay(50);                     
  } 
}
