Resolved by DJ Sures!
I got my head all back together and the neck, etc. I have a battery going through a 640 ohm resistor to a female extention plug. I plug this in to test the LEDs. Each one worked very good but one did not. I checked reverse polarity on the circuit and the LED worked. I did not want to take the head all apart again (hassel). So , I simply turned the plug around not realizing if i were hurting something or not. But, it did not seem that it would damage the EZB because I was simply swapping ground and signal. I can't see very well, I may have plugged a plug in shifting one pin over. that would connect ground to hot or signal to hot.
Anyway, boiling it down, All of my digital pins do not work anymore.
Any ideas? I am thinking voltage regulator blown, I hope it is not the cpu. I am going to run the test that D.J. has and try to figure it out. The lights blink red and blue and it connects up. So , the bluetooth is working.
Wish me luck.
If the lights are blinking, it most likely is the voltage regulator. Let me know if you have trouble replacing it and we'll see what we can do to help you out
Do some work but not others?
I got my five volts on there. Also, ALL of the digital pins do not work. I have not checked the analog.
@ DJ, what are the voltage regulator values, I know one is 5 volts. Is the other 3.3 volts? I am getting 3.3 where it says 3.3 on the print. And, I am getting 5v where it says 5v. Also, I am showing 7.2v coming in.
One regulator has 7.2v coming in and 5 volts going out.
The other one has 5v coming in and 2.19 going out. That is the one I think is bad. I need to know the value so I can change it. I have a lot of regulators in stock. This is probably the 3.3 regulator. But, I need to know.
Thank you.
;)
Please, What is the voltage value of the one closest to the plug?
I'm on a plane. Landed between layover. You need to learn patience movie maker
5 volts is the ezb except for the pin labelled 3 volts. You know these answers because the board is labelled
sorry.
I still don't understand. You are saying you have a 5 volt regulator ie; 7805. And you have a 3.3 volt regulator?
VR1 is the one that has the problem. But, is it a 3V regulator or a 3.3 volt regulator? I just want to be sure before I purchase it. I have plenty of 5 and 12v regulators.
I see two. I know which one is 5 volts, but I have to be sure the other is 3V. My eyes are bad and I don't see it labeled ,but I will look again.
Thanks, and sorry to bother you on the plane.

The voltage out of both of the heat sync regulators is 5 volts. The voltage out of the small regulator is 3 volts. These voltages are labeled.
