Code Listing
The simplest way to control a BASIC Stamp output pin is with the
commands require a pin number parameter. Let's take a look at Listing 1a to see
' {$STAMP BS2}
' Program: LED Blink.BS2
' Purpose: Blinks an LED connected to BASIC Stamp pin P15
' ---------------------------------------------------------------
Start:
As you can see, the program starts by making pin 15 go high (5 volts). This will cause the LED to light. In order
for us to see it, though, we must insert some time before we turn it back off. We can create a short program
delay with the
that follows is the delay time in milliseconds (
LED to stay lit for one-half second.
