ESP32-Bluetooth-selfie-pin

Take pictures on distance with your smartphone.

You can buy this kind of selfie remote button in Alibaba....

... but its more fun to make one by self.

How to use

You go to Bluetooth settings in phone and pair it. (it showup as "EPS-selfiepin") You will hear a melody when it connect / disconnect. Open camera app and push button on ESP. ESP will send "volyme up" button to the phone app. That is the button for take pictures in android phones. I have not test on iphone.

Here is schematic

It use ESP32 devkit V1 DOIT. If you use another ESP32 board, the pin number can be diffrent. It can be powerd by USBcable or 5 Volt by pin gnd/vin
