Ducks in the pond

In this assignment, we decided to use Linkage Example#1 on the website for moving the ducks forward and backwards. Also, we automated the clock using a servo motor and set the delay between each round of the clock to 500ms.

Components:

1 Arduino Uno Microcontroller

1 Bread Board

1 Servo Motor

Connecting Wires

3 Ducks

Wood and screws to make the linkage

Hard board base

Other stationaries for decoration

#include <Servo.h> 

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

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

void setup() 

{ 

 myservo.attach(7);  // attaches the servo on pin 7 to the servo object 

} 

void loop() 

{ 

  for(pos = 0; pos < 130; pos += 1)  // goes from 0 degrees to 130 degrees 

  {                                  // in steps of 1 degree 

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

    delay(15);                       // waits 15ms for the servo to reach the position 

  } 

  delay(500);                     //wait for some time before going back

  for(pos = 130; pos>=1; pos-=1)     // goes from 130 degrees to 0 degrees 

  {                                

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

    delay(15);                       // waits 15ms for the servo to reach the position 

  } 

  delay(500);                      //wait for some time before going back
