Arduino Servo Basic

by Rezz on October 12, 2011

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

Parts List;
1) 1x Arduino
2) 1x Servo Motor
3) Jumper wire

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;
Negative – Black/Brown
Positif – Red
Signal – Yellow/Orange/White/Blue (this cable connected to digital input)

Servo signal connected to digital pin 9 which is PWM, it works too with other non PWM digital pin.
