Arduino Servo Basic Code

In arduino projects, you might add servo to your projects. This short tutorial, show you the basic how arduino and servo works together.

Instruction;
1) Connect all jumper wire as shown in diagram.

2) Connect the signal wire from servo to digital pin 9.

Upload this code to your arduino

// include the library code:
#include <Servo.h>

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

void setup(){
  myservo.attach(9);  // attaches the servo on pin 9 to the servo object
}

void loop(){
  myservo.write(0);     // sets the servo at 0 degree position
  delay(1000);          // waits for the servo to get there
  myservo.write(90);    // sets the servo at 90 degree position
  delay(1000);          // waits for the servo to get there
  myservo.write(180);   // sets the servo at 180 degree position
  delay(1000);          // waits for the servo to get there
  myservo.write(90);    // sets the servo at 90 degree position
  delay(1000);          // waits for the servo to get there
}

Servo cable have 3 wire, make sure you connect it properly;
