RCTIME command Basic Stamp 2

Phlis

Hi all,

I am a starter to Basic·Stamp 2.

I am working on a project using the RCTIME command, to light up an LED within a certain RC range (25 to·30) and turn off the LED out of this range. I adjust the 10K potentio meter (with a 0.1UF capacitor) connected to the Basic Stamp 2 input pin 4. I can vary the speed by turning the potentio meter with this command:

' {$STAMP BS2}

··· speed VAR Word
·· Loop:
··· HIGH 4 'discharge the capacitor
··· PAUSE 1 'for 1 milisecond
····RCTIME 4,1,speed
··· DEBUG ? speed
··· IF (25>speed<30) THEN do
··· do:
·· HIGH 12
·· RETURN

What command do I use to turn off the LED when the speed is out of this range?

Your help is much appreciated.

Thank You.

Just a suggestion... try something like this:

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

speed VAR Word

DO
·HIGH 4
·PAUSE 100 'need more time on your pause command
·RCTIME 4, 1, speed
·DEBUG ? speed
·IF(speed > 25 AND speed < 30) THEN
· HIGH 12
·ELSE
· LOW 12
·ENDIF
LOOP

END

I haven't tested the above but it should work... it'll keep the LED on if its in range, or if its out, turn it off.
