Blink example ​(3.0 branch only)

​noOfBlinks = 0 
pin = 0 
blinkDelay = 1000 
[top] 
print "How many times to blink"
textbox noOfBlinks 
print "Pin To use" 
textbox pin 
print "Blink Delay" 
textbox blinkDelay 
button "Blink Me Please", [blinkMe] 
button "Exit", [getMeOutOfHere] 
wait 
 
 
[blinkMe] 
for x = 1 to noOfBlinks
  io(po,pin,1)
  delay blinkDelay 
  io(po,pin,0) 
  delay blinkDelay 
next x
wait 

[getMeOutOfHere] 
end

This will prompt the user to select the pin, blink duration and number of blinks to execute.

GPIO 2 is normally connected to an LED on the node mcu boards.
