In this Instructable I will show you how to build a simple device that you can use to control the orientation of a camera to follow your movements.

How it Works:

Your cellphone has an orientation sensor in it, aka a Compass. Using an App designed using MIT App Inventor we will use this compass to determine your orientation to the camera and then transmit this information to the Arduino via Bluetooth. The Arduino will rotate the camera which is mounted to a Servo Motor toward the phone.

Watch the Demo of the Arduino Camera Man on YouTube

Step 1: Wiring It Up

First we will need to wire everything up.

Let's start with the servo motor.
You should have three wires coming from the Servo.
Ground- usually Black or Brown.
VCC - usually Red
Signal - usually Yellow or Orange

Connect the Ground wire to - Arduino GND
Connect VCC to - Arduino 5V
Connect Signal to - Arduino pin 9

Tip - You could choose to power the Servo Motor externally using a battery instead of the Arduino, if your servo motor is large or the camera is heavy the Arduino may not be able to supply enough amperage to power the servo motor and could damage the Arduino

Step 2: Wiring Up the Bluetooth Module

Next we need to hook up the Bluetooth Module

GND connects to - Arduino GND
VCC connects to - Arduino 5V
TXD connects to - Arduino pin 10
RXD connects to - Arduino pin 11

Tip: I am using the HC-06 Bluetooth module which can handle 3.6 volts to 6 volts. Also, when connecting your cellphone to the bluetooth module for the first time make sure to make your phone is visible when searching for a new bluetooth device to connect to. When asked to enter a pin code, most bluetooth modules use "1234" or sometimes "0000"

Step 3: Download the Arduino Code and the App

Next we will need to download the Arduino Code from Github

You can get it here

Next, you will need to download the App from MIT App Inventor

You can get it here

or you can search the App Inventor Gallery by searching for "Arduino Camera Man"

Step 4: Optional 3d Printed Camera Mount

If you happen to have the same or similar camera you can download the 3d printer file here at Thingiverse

    Tip 9 months ago on Step 2

    The RDX pin is only rated for 3.3v. Using 5.5v can be harmful for the HC-06. I always add a voltage divider to bring the voltage down to 3.3v for this one pin.
