;********Interactive Artwork ala Monster with two LDR eyes with a voltage divider*****************

;Change Code
;Change trigger_Sensativiy upwards to make less sensative to light changes
;Change the light Reading_Delay_Time downwards for capturing quicker motion
;Change START UP ROUTINE with a TUNE or Blink LED on pin0 ?
;Change the sound of LEFT and RIGHT Routines

;*************Create Symbols*************************************************** 

symbol light_Reading1 = b1          	;Takes first light reading
symbol light_Reading2 = b2		;Takes second light reading
symbol trigger_Point_Left = b3 		; Is light reading2 MINUS the trigger sensativity
symbol trigger_Point_Right = b4 		; Is light reading2 PLUS the trigger sensativity
symbol trigger_Sensativity = b5  		; how far light change is above or below average before triggering output
trigger_Sensativity = 7				;Change trigger_Sensativity upwards to make less sensitive 
symbol Reading_Delay_time = 50 		; Change the pause time between light readings 

;*********Start up Routine********************************************************

;Put start up routine Here

;********Start Main loop*********************************************************
main:

readLDR:
readadc  4, light_Reading1  			;First light reading
pause Reading_Delay_time 			;Delay time between readings in milliseconds
readadc  4,  light_Reading2 			;Second light Reading
pause 20

TriggerPoints:
trigger_Point_Right = light_Reading2 + trigger_Sensativity      ;make trigger for Right,  Set trigger sensativity at the Top of Code
trigger_Point_Left = light_Reading2 - trigger_Sensativity 	;make trigger point for Left

;debug

Decide: 										;Decide to go routine left or right or back to Main
if light_Reading1  <   trigger_Point_Left then gosub left  
if light_Reading1  >  trigger_Point_Right then gosub right

goto main

;************Sounds when motion detected*********************************
right:
pulsout 0,40
tune 0,2,(0,2,4,6,7,9,11,16) 			;Make your own Tune/sound/PWMOUT for right
nap 4
return

left:
pulsout 0,40
tune 0,2,(16,11,9,7,6,4,2,0) 			;Make your own Tune/sound/PWMOUT for left
