Hi, I have made this arduino robot which relys on an HC-05 for input. When I connect the HC-05 to my phone it just stops blinking and after a few seconds it shows device connection was lost. My Code and Schematic Digram. Have you any ideas about what may be causing the sensor to just stop? TIA.

HC-05 Keeps on disconnecting

Well, the 9V probably killed it and the 27V drove a spike through it's heart.
