Microcontroller Issues

[Memelord420 1]

So, basically I'm trying to do this thing where I have a microcontroller and I want it always receiving, and when it receives a certain message, I want it to output redstone. I've got all the right components, and it doesn't crash on boot, but when it receives a message, it crashes. The code is simple, and yes I'm doing the component.proxy() thing. 

Full code:

local modem = component.proxy(component.list("modem")())
 
local redstone = component.proxy(component.list("redstone")())
 
modem.open(123)
 
local name, _, from, port, _, message = computer.pullSignal("modem_message")
 
if message == "hi" then
  redstone.setOutput(1,10)
else
  redstone.setOutput(1,0)
end

Can't delete this thread, but after a lot of experimenting I fixed it by just adding a simple while loop.
