For monitoring a single pin, look at the BUTTON command.

You can also monitor a single pin with INx, a group 4 pins with INA, INB,INC,IND, and a group of 8 pins with INL or INH.

Good explanation of each of these in the Help file in the Stamp programming environment.

Cheers,

You question is a little unclear. Did you try

IF IN3 = 1 THEN ' HIGH
   ' do something
ELSE ' LOW
   ' do something else
ENDIF

Hi all,

thanks for replies,

yes you are correct using INL would work as im usind INB already & can cut out some lines & subroutines but i'm having trouble getting INL to Run ( problem with variables i think ???)

Has anyone got an example of INL to get me Started,i used this to get on right track with INB

·File...... SW21-EX14-Debounce.BS2
'·· Purpose... SCANNING AND DEBOUNCING MULTIPLE INPUTS
'·· Author.... Parallax Stamp Works EXPERIMENT #14

But no info on using INL inputs 0-7, i tried to mod my working INB but not getting anywhere
