reading value on a specific pin

Archiver

how can i read a DC(0 or 5V) input from a specific pin?

Here is what we have:
Our basic stamp will be supplying either a high or a low to pin 13.
From here we want to be able to read from pin 9 to see if pin 13 is on
or off. This sounds trivial I know, but I need to be able to do this.

So far when we tried the SERIN command. It will not read the DC
voltage (on or off 5v). Is there another command, and if so how would
it be done.

Connect pin 9 and 13 together via a 10k resistor, then in your code...

set pin 13 as output and pin 9 as input...

code sample...

if in 9 = 1 then dosomething ' will do something if the pin 13 is high
'put code here for when pin 13 is low.

dosomething: 'put code here for when pin is high.

Someone else may have a simpler answer, but this should work.

Cheers,
