What do you expect to do with 'bluetooth'?

[Nick_Pyner]

Delete the following

@sadk_sadk

for debuging purposes

and connect HC-05 to pins 0,1 only after you have uploaded the programme. No "conversion" needed.

[engmahmoudsaber]

First, put this library
#include <SoftwareSerial.h>
Second, make sure that while uploading the code, you disconnect pin 0,1 until the code is uploaded, and then reconnect them

[sadk_sadk]

Send a byte from Android to Arduino via bluetooth, then arduino outputs to shift register

[sadk_sadk]

I did ... not happen nothing

[Nick_Pyner]

I said what I said on the assumptions that

1. the code you posted actually works as intended
2. you know how connect HC-05 in the proper manner.
   The latter may not be the case. Make sure you connect Rx>Tx and Tx>Rx.
   
   There really isn't much else that can go wrong! I note with relief that you have not said that you don't use HC-0x. I'm afraid that was an assumption I made that might have been one too many. I also hope you are not using something IOS.

Your code receives serial input with wires, from the monitor, and acts accordingly with the LEDs. Using Bluetooth enables you to do the same thing without wires.

Pins 0,1 and the USB connection to the serial monitor share the same hardware serial port. Arduino just listens to the port and neither knows nor cares where the signal actually comes from - or how it gets there.

I urge you to studiously ignore reply #4. It is rubbish and suggests by implication that you do something stupid.
