Re: To build a high speed photography project using Bluetooth

I am not clear why a voltage regulator is being used here as I was under the impression that the Arduino is not expecting a regulated 5V on Vin. If a regulated 5V is to be used it should be via the 5V pin, which appears to be unused here.

The Arduino has its own inbuilt regulator and expects to see 7V - 20 12V (edit) on Vin. Am I missing something (quite possible)?
