Some how like a sunlight clock,
Were the screen gets gradually brighter nearer the wake up time another idea would link it to ioi board to control leds that get brighter .
that coupled with sound getting louder as you get near wake up time .
I have a old Android pad ,and it would be nice to wake to sound and light gently coming in ,in the morning Ahhhhh 
IOI is on google play
