While I was in boredom, I made a simple microcontroller program.
microcont.lua
local rs = component.proxy(component.list("redstone")())
while true do
if rs.getInput(3) > 0 then
computer.beep()
end
computer.pullSignal()
end
When the microcontroller receives a redstone signal from it's front, it beeps.
Took me some time to figure out how to make an actual program for microcontrollers that doesn't error out after a few seconds.
(also, this is my first topic!)
