Very Basic Pan Tilt Using Arduino

for this instructable you will be learning the basics of arduino and codes for arduino.


video of pan/tilt arduino project (careful, this video contains aweful impressions of batman)

if anybody wants me to put up more photos on this project please message me.

Step 1: Supplies and Wiring

things you will need:

-2 sub-micro servo motors

-one pan/tilt bracket

-various jumper wires

-mini breadboard

-joystick

-arduino

-(optional) batman's head, two LEDs, and a tiny hat

Step 2: Description of Wiring

i don't have any photos for this process but i will make some if i am asked enough.

wire the data wire of the bottom servo to pinhole ~9 and wire the data wire of the top servo to pinhole ~10, the data wire is usually the white or yellow wire of the servo.

the y axis pin of the joystick goes to A0, x axis pin goes to A1

for powering everything connect allpositives to the 5V pinhole on the arduino and allnegatives to the GND pinhole on the arduino, i used a mini breadboard for this

Step 3: CODE

below is code for the arduino, i suggest using this stuff if you want your cool new pan/tilt machine to work!

code:

// Controlling two servos positions using two potentiometers or a joystick
// modified knob example by kevin jones original code by Michal Rinott

#include

Servo myservo0;  // create servo object to control a servo
Servo myservo1;

int potpin0 = 0;  // analog pin used to connect the potentiometer
int potpin1 = 1;
int val;    // variable to read the value from the analog pin

void setup()
{
  myservo0.attach(9);   // attaches servo to pin 9
  myservo1.attach(10);  // attaches the servo on pin 10 to the servo object
}

void loop()
{
  val = analogRead(potpin0);            // reads the value of the potentiometer (value between 0 and 1023)
  val = map(val, 0, 1023, 0, 179);     // scale it to use it with the servo (value between 0 and 180)
  myservo0.write(val);                  // sets the servo position according to the scaled value
  delay(25);                           // waits for the servo to get there
  val = analogRead(potpin1);            // bananas are high in potassium
  val = map(val, 0, 1023, 0, 179);     //
  myservo1.write(val);                  //
  delay(25);                           //
}
