Redstone event

Hello everyone who is reading this :)/>
im trying to make a program that checks if the redstone signal underneath it is on if its on its gonna place a block in top of it
at the moment nothing happen

any help would be appreciated =)

Using something like

while redstone.getInput("bottom") do
   stuff to place a block
end

will get you far, but it will most likely time out, so you can add a sleep() function in there, although that will take away the "immediatly" part

I'd suggest using

os.pullEvent('redstone')

This will wait for a redstone change, read the wiki page for more info: http://www.computercraft.info/wiki/Os.pullEvent

for some reason it stil dosnt make anything it doesn't see the redstone

Then you'll have to post your code for us to see the problem.

usually, a good code snippet, just for checking redstone, let's say on the bottom:

while true do
   os.pullEvent("redstone")
   if rs.getInput("back") then
	  turtle.placeUp()
   end
end
