Tilt sensor

hi,

we few students bit lost in arduino world our project.
we making lamp more or less represent ancient hourglass - light in lamp represent sand.

(see picture) when level 1 (each level  has 2 led's) fade out 100 % led light 0 %, want straight after level 6 fades in 0 % led light 100 % led light. same procedure level 2 & level 5 , level 3 , level 4.

each fading (in , out) should take 3 seconds , between each level there should 5 minutes before lights up.

since hourglass want procedure repeated when flip lamp, , here bit lost. have tilt sensor, problem how code lamp 'start on again' when twist normal hourglass. sand starts falling down again (in case our led's)

if have input on both led coding tilt sensor (how code in able work) please leave comment. tips helpful.


#include <softpwm.h>

void setup()

}


what have:

arduino micro
6 mosphets
12 leds
tilt sensor etc

maybe if read this, , add tags code, more chances interested in you.
