Lighthouse?

tweek

Im new to Basic Stamps. I recently bought a homework board and have been having fun with it,(led's and such). I recently built a "lighthouse circuit", (ALL info obtained from discoverycircuits,David Johnson) http://www.discovercircuits.com/DJ-Circuits/lighthouseflash5.htm
It slowly ramps up the current to an LED, then flashes it bright, then dims again, like a rotating lighthouse. ,but,
I was wondering if it would be possible to do this same thing on the Homework board? All I really figured out so far on/off and pause durations, and freqouts, to make them flash a bit.
Thanks

Connect LED to pin 15 and a 220 ohm resistor from led to ground. This should simulate what you are looking for i think.

' {$STAMP BS2}
' {$PBASIC 2.5}

j VAR Byte
k VAR Byte
main:
j=0
k=1
FOR i=1 TO 3000 'fade up slow from dim
 PULSOUT 15,k
 j=j+1
 IF j=15 THEN
  j=0
  k=k+1
 ENDIF
NEXT
FOR i=k TO 300  'fade up fast
 PULSOUT 15,i
NEXT
FOR i=300 TO k  'fade down fast
 PULSOUT 15,i
NEXT
j=0
FOR i=3000 TO 1 'fade back to dim slow
 PULSOUT 15,k
 j=j+1
 IF j=15 THEN
  j=0
  k=k-1
 ENDIF
NEXT
GOTO main

Think Inside the box first and if that doesn't work..
Re-arrange what's inside the box then...
Think outside the BOX!
