Hello,
Does anybody know how to write an IF..THEN that will watch the state of a
pin. I don't see it in the manual. I don't know how to read just one pin.
Thanks
Kevin

Assuming Pin 0
if in0 = 0 then stop
if in0 = 1 then go

Here's another approach that uses less code:
BRANCH In0,[noparse][[/noparse]Stop, Go]

a variable and branch according to the value of the variable. I use this on
one of my robots to read all of the line sensors at once -- works very well
and prevents me from having to check each pin one at a time.
Buy / beg / borrow / steal the Nuts & Volts of Basic Stamps books -- lots of
good info you won't find in the Stamp manual or in the online documentation.

Any BS2P package weekend deals coming up? I was thinking about a BS2P40 and
one of those I2C clock / RAM modules. Might even design and build a real
circuit board for this robot.
For anyone interested, Radio Shack has the "Spy Kids" RC mini-van for $10
off -- now $30. Lots of room internally for robot guts and a sunroof that
looks like it would be good for an LCD display. The sucker is fast too, and
has a turbo mode. Unfortunately you pay more for a NiMH battery and charger
than for the car.
