Bluefruit EZ-Key HID + Arduino == Android password unlock screen

Just a quick experiment to unlock an Android phone secured with a password via bluetooth.

So this is testing the Bluefruit EZ-Key bluetooth module.
I've got it wired up here.
It's a very simple way of sending the password
for my phone through the serial connection
from an Arduino into the Bluefruit.
The Bluefruit is really just acting as the bluetooth mechanism here.
And it will show up as a keyboard on this,
so it is already synced [paired] to the phone.
And, it is a very interesting way to unlock a phone, I guess.
More of a curiosity than anything very practical.
But just push this button here [click] and the phone will activate.
Sometimes it actually types the password in right away but, [click] it did it right there.
And there it goes, it's unlocked.
So we shut it,
[click]
push the password,
and there it goes.
It's really great at a desk, I've come to find.
I sit down at the desk and just push the button and then my phone unlocks.
It's kinda cool.
Probably not very secure, but
If my desk isn't secure I've got bigger problems to worry about right now.
Anyway, thought it was fun. Thought I'd share.

Awh,
and sometimes it messes up like that. [click]
Haha.
