Hello I'm new so hi.

Anyways I'm a complete novice when it comes to coding, I can barely code a password lock for a door.

I have been searching the internet for a premade code on how to have the computer countdown 3(ish) hours, well 2 hours and 50 minutes to be precise, then send out a redstone pulse from the back then sleep for like 5 minutes and on an infinite loop. So once it is done sleeping it restarts itself and that goes on forever, well that's the dream atleast. Also with the remaining time displaying on a monitor.

Any help would be greatly appreciated />

while true do --Loops the program
sleep(10200) --Sleeps for 2h50m
rs.setOutput("back", true) --Activates the back
sleep(300) --Stay activated for 5m
rs.setOutput("back", false) --Deactivates the back
end

There you go!

m = 50
h = 2
for i=1, 170 do --170m = 2h50m
    term.clear() --clears the screen
    term.setCursorPos(1, 1) --sets the cursor to 1,1
    print("Hours: "..h) --prints how many hours are left
    print("Minutes: "..m) -- prints how many minutes are left
    sleep(60) --sleeps for 1m
    if m == 0 then --if the minutes hit 0 then it set minutes to 60 and hours to hours -1
	    h = h-1
	    m = 60
    end
	    m = m-1 --makes m one less then m
end

just do monitor (side of computer the monitor is on) (what you named the program)

I tried making one too! /> But, I'm not very good with lua so this is probably really bad /> Sorry if I did it wrong..

h = 2
m = 49
s = 60

function check()

if s <= 0 then
  m = m -1
  s = 60
end

if m < 0 then
  h = h-1
  m = 60
end

if h < 0 then
  print("Standing By...")
  redstone.setOutput("back", true)
  sleep(1)
  redstone.setOutput("back", false)
  sleep(300)
  h = 02
  m = 49
  s = 60
end
end
while true do
term.clear()
term.setCursorPos(1,1)
print(h..":"..m..":"..s)
sleep(1)
s = s-1
check()
end

Just run that on the monitor />

Edit: Oh and.. If someone could point out what I could do better.. That would be great /> I'm trying to get better.

you may want to switch

if h < 0 then
  redstone.setOutput("back", true)
  sleep(1)
  redstone.setOutput("back", false)
  sleep(300)
  h = 02
  m = 49
  s = 60
end

to

if h == 0 and m ==0 and s == 0 then
  redstone.setOutput("back", true)
  sleep(1)
  redstone.setOutput("back", false)
  sleep(300)
  h = 02
  m = 49
  s = 60
end

i think that should work

Isn't it basically the same thing? Since it won't print anything once the hour is -1. So it'll show up the same?

Edit: I changed some of the code so that it won't just stay frozen at 0:0:1. The first post I made has been updated />
Edit 2: Also, You could save this:

shell.run("monitor", "right", "timer")

as a program called 'startup' and it would automatically start the program on the monitor. Remember to change "right" to whatever side you have the computer on and "timer" to whatever you named the program.
