Ever wanted to build a Face Tracking Robotic Arm or Robot by simply using Arduino and not any other programming like OpenCV, visual basics C# etc? Then read along, in this project we are going to implement face detection by blending in the power of Arduino and Android. In this project, the mobile camera will move along with your face with the help of servos. The advantage of using the Android Mobile Phone here is that you do not need to invest on a camera module and the whole image detection work can be done in the phone itself, you do not need your Arduino connected to your computer for this to work. Here we have used Bluetooth Module with Arduino to communicate with Mobile wirelessly. The Android application used in this project was created using Processing Android, you can either directly install the application by downloading the APK file (read further for link) or put on your programming cap and make your own more appealing Android Application using the Processing Code given further in the Tutorial. Learn more about Processing by checking our previous Processing Projects. By the end of this tutorial you will have a Mini Tilt and Span Robotic Arm that could track your face and move along with it. You can use this (with further advancement) to record your vlog videos or even take a selfie with the rear camera of your mobile phone since it positions your face exactly at the centre of your mobile screen. So!! Sounds interesting? Check the Demo Video at the end this tutorial to see it working. Let’s see how we can build one… I have tried my best to make this project to work as simple as possible, anyone with minimum knowledge on hardware or coding can use this guidelines to make this project work in no time. However once you make it I suggest you to get behind the codes so that you can really know what makes this thing work and how. “
