I want to Control Android Mobile Camera shutter using Arduino over Bluetooth. So i can click photos using arduino.

I have HC-05 Bluetooth Module and Arduino Nano/Arduino leonardo. enter image description here

The Connection as shown in figure.

The Android mobile successfully connected to Bluetooth Module but i am not found any code to control camera or any button on android mobile.

  • You'll need an Android APP to interface with the bluetooth and receive instructions to control the camera. Maybe the play store has something. If not, you'll have to learn Android programming.

  • Volume buttons can also use for camera shutter, so if arduino can control volume buttons then it also use as camera shutter.

    I think those cheap BT shutter buttons act like a keyboard, and send the spacebar keycode (if I remember correctly)

I am trying out Camera Pro. It allows shutter control on Android over Bluetooth. I just got an Uno R3 and and HC-05 so I have not wired it up to try it.

There are example sketch and detailed docs here.

  • Programming Android is too much work (PITA, really). I like your solution even if I have to pay for it. I grow tired of downloading IDE updates every other week, dealing with API changes from one release to next one, and having to redesign apps to the latest fad ("material" any one?).
