Simple counter and some thing you could do with this

count = 0

count = 0
while true do
  count = count + 1 --add 1 to count
end

count = 0  --sets count to zero
while true do  --main loop
  count = count +1  --add 1 to count
  print(count)  --prints count
end  --ends loop

count = 0  --sets count to zero
while true do  --main loop
  term.clear()  --will clean the screen
  count = count +1  --add 1 to count
  print(count)  --prints count
end  --ends loop

count = 0  --sets count to zero
while true do  --main loop
  term.clear()  --will clean the screen
  count = count +1  --add 1 to count
  print(count)  --prints count
  sleep(1)  --waits 1 second
end  --ends loop

mon = peripheral.wrap("top")  --connects to the monitor on top of the computer
sec = 0  --declare variables
min = 0
uur = 0

mon.setTextScale(1.5)  --set the text scale of the monitor to a 1.5 magnification

term.redirect(mon)  --redirect the output ot the monitors
while true do  --main loop
  term.clear()  --clear the screen
  term.setCursorPos(1,1)  --set the cursor to the left upper corner

  if sec==60 then  --if 60 seconds have past add 1 to minutes and set seconds to 0
	min = min + 1  --adds 1 to minutes
	sec = 0
  end --ends if

  sec = sec + 1 --counts the seconds

  if min==60 then --if 60 minutes have past add 1 to uur(hours) and set minutes to 0
	uur = uur + 1  --adds 1 to uur(hours)
	min = 0
  end
  --prints everything
  print("time is: ")  
  print(sec.." seconds")
  print(min.." minutes")
  print(uur.." hours")
  sleep(1)  --sleeps for 1 second
end

1. adds 1 to second
2. if 60 seconds have past it will add 1 to minutes and set seconds to 0
3. if 60 minutes have past it will add 1 to uur(hours) and set minutes to 0
4. prints the variables
5. sleeps 1 second before going back to step 1

meter = 0

while not turtle.detect() do
  meter = meter + 1

  term.clear()  --clear the screen
  term.setCursorPos(1,1)  --set the cursor to the left upper corner

  print("traveled "..meter.." meters!")




  turtle.forward()

function clock()
	for i = 0,i+1,1 do
		if i > 60 then
			i = i+40
		end
		if i > 6000 then
			i = i + 4000
		end
		if i > 240000 then
			i = i + 760000
		end
		print(i)
	end
end

count = 83
while true do
count = count -1
mon.setCursorPos(1,10)
mon.write(count)
sleep(1)
end

if count == 0 then
stop count
end

if input == "mellohi" then
	rednet.broadcast("mellohi")
	mon.setCursorPos(1,2)
	mon.write("Now playing: Mellohi")
	mon.setCursorPos(1,6)
	mon.write("Please wait for current song to finish")
count = 83
while true do
	count = count -1
	mon.setCursorPos(1,10)
	mon.write(count)
	sleep(1)
end
sleep(83)
mon.setCursorPos(1,2)
mon.write("Please select a song")
mon.setCursorPos(1,6)
mon.clearLine()
end

count = 83
while count > 0 do -- this_is_ the adjustment :P/>/>
count = count -1
mon.setCursorPos(1,10)
mon.write(count)
sleep(1)
end

Just let the loop run while count is greater than zero. If you want to include zero change 'while count > 0 do' to 'while count >= 0 do'.

instead of print for the click wouldn't you need mon.write()? or do you not need that as you have redirected the terminal using term.redirect()?

local mon

local phase = {}
phase.planting = {['next']=phase.resetBuilder, ['duration']=40, ['name']="Planting Phase"}
phase.resetBuilder = {['next']=phase.growing, ['duration']=2, ['name']="Reset Builder Phase"}
phase.growing = {['next']=phase.harvesting, ['duration']=1200, ['name']="Growing Phase"}
phase.harvesting = {['next']=phase.planting, ['duration']=200, ['name']="Harvesting Phase"}

local currentPhase = phase.planting

local function printPhase(cPhase, timer)
  mon.clear()
  mon.setCursorPos(1,1)
  mon.write( string.format("%s: %d seconds left.", cPhase.name, cPhase.duration-timer) )
end

local function findMonitor()
  for _,side in pairs(rs.getSides()) do
	if peripheral.getType(side) == "monitor" then
	  return peripheral.wrap(side)
	end
  end
  error("No monitor found!")
end

mon = findMonitor()

while true do
  for i=1,currentPhase.duration do
	printPhase(currentPhase, i)
	sleep(1)
  end
  currentPhase = currentPhase.next
end

That was a very stupid mistake I made. :)/>/> Edited in the previous post.
{} defines a table. It holds the different phases in it. Each phase is also a table holding a reference to the next table (phase), the duration to wait and the name. Look up on lua tables to understand this better. :D/>/>
