ProximityBand-Arduino

Usage:

Setting the LEDs brightness:
While the device is disconnected, press and hold the button.
All three LEDs will light up, set the switch to position 1-2-3.
Position 1: Min LED brightness.
Position 2: Medium LED brightness.
Position 3: Max LED brightness.
Let go of the button and the change is saved to memory.
The brightness is retained even after the device is turned off.

Setting silent / vibrate / sound mode:
While the device is connected, set the switch to position 1-2-3.
Position 1: Silent mode.
Position 2: Vibrate mode.
Position 3: Sound mode.

Setting do-not-disturb mode:
While the device is connected, press and hold the button.
Set the switch to position 1 to turn on DnD mode.
Set the switch to position 2 or 3 to turn off DnD mode.
Let go of the button.

Turning off the alarm:
In any case while the alarm is turned on, simply press the button.
This will stop the vibration and light flashing on the Proximity Band as well as the Android device (if it is still connected).

TODO:

1. Make the LEDs flash in unison or some other pattern instead of on their own induvidual timers.
2. Make the motor pulse in some preset pattern.
3. Make the LEDs fade in and out.

Technical details:

Determining if the Bluetooth connection is active:
If any data via BLE is recieved, a timer is set for 1 second.
If no other data is recieved after the timer is done, this means that the connection is not active.
In this case the alarm will be acivated.
