Why won't my ps4 controller connect to my ps4? [duplicate]

I bluetooth paired my ps4 controller to my ps4 just fine. Then i deleted the bluetooth controller account (ps4 controller)off of my ps3. Now no matter what I do my controller won't work for the ps4. I click the home button and it blinks once then turns off. Someone please help me before I loose it.

I think that pushing the reset button on the controller might help you.

From this answer:

If your controller won't pair, won't respond, or is displaying a flashing light, please follow the instructions on how to reset the controller:

1. Turn off the PlayStation 4.
2. Locate the small reset button on the back of the DualShock 4 near the L2 shoulder button.
3. Use a small, unfolded paper-clip or something similar to push the button (the button is inside a tiny hole).
4. Hold the button down for a couple of seconds and release.
5. After resetting the controller, re-pair the controller with the PS4 by connecting the USB cable to the controller and the system, and turn the PS4 on.
6. Press the PS button to log in to the PS4
