I'm trying to make a nuclear powerplant (using industrialcraft) with a main console, this console is going to have a gui and options to control reactor cooling and doors, shutters, power distribution etc. Of course one redstone output won't be enough to make this work. So I decided to make it transmit messages via wireless modems and rednet to other pc's that then execute commands, in this case mostly activating redstone currents. Being new to coding in general, how could i do this?

Sender:

rednet.open("side of modem")
rednet.send(*INSERT ID OF RECEIVER*, "doors")

Receive:

rednet.open("side")
while true do
a, b = rednet.receive()
if b == "doors" then
  redstone.setOutput("back", true)
  sleep(1)
  redstone.setOutput("back", true)
end

To add more commands, add this to sender:

rednet.send(*INSERT ID OF RECEIVER*, "command")

and this to receiver:

if b == "command" then
  --add code here
end

you mean false? true then false, or then doors would be stuck open.

To add more commands, add this to sender:

rednet.send(*INSERT ID OF RECEIVER*, "command")

and this to receiver:

if b == "command" then
  --add code here

this script is not working, why doe it expect to end at line:2?

That wasn't a full script - I think ComputerCraftFan11 intended it to be something to lead you in the right direction, not for you to use it as it is.

Anyway, fixed version (he forgot to end the while true statement):
Again, this is also to lead you in the right direction, not be a complete working application.


rednet.open("side")
while true do
  local a, b = rednet.receive()
  if b == "doors" then
	redstone.setOutput("back", true)
	sleep(1)
	redstone.setOutput("back", false)
  elseif b == "reactor off" then
	redstone.setOutput("right", false)
  elseif b == "reactor on" then
	redstone.setOutput("right", true)
  end
  -- Add more elseif statements to add more commands
end


rednet.open("side")
rednet.send(ID OF SENDER, "doors")
rednet.send(ID OF SENDER, "reactor on")
sleep(10)
rednet.send(ID OF SENDER, "reactor off")
