[Question][Solved]How to get a string to output through redstone signal?

I wanna make it so that when the computer recieves a redstone signal at the 'back' side, it will output a message saying something like 'signal recieved'. How would i do this?

You can use os.pullEvent() :

while true do
  event, param = os.pullEvent()
  if event=="redstone" then
    if param=="back" then
	  print("signal recieved")
	  break
   end
  end
end

Is there any other code that goes before that? i just tried it and connected signal to it and it does nothing?

os.pullEvent doesn't return any parameters for the "redstone" event

You'll need something more along the lines of this:

local loop, HadPower = true, redstone.getInput("back")
while loop do
   local e = os.pullEvent("redstone")

   if e=="redstone" then --Just in case, should always be true
	 local power = redstone.getInput("back")
	
	 if power and not HadPower then
		--We got a pulse
	 elseif (not power) and HadPower then
		--We lost a pulse
	 end

      HadPower = power --Nearly forgot this bit :)/>/>
   end
end

THANKS!
