Play disk with pressure plate signal

Hi, im kind of new to ComputerCraft, but understand most of the basics.

Right now im trying to make a disk play by the DJ command, when stading on a pressure plate next to a computer, but i cant seem to work it out.

I tried to code it myself, but im not sure how to make it work.

local side = "right"
while true do
term.clear()
term.setCursorPos(1,1)
write("Waiting...")
local input = redstone.getInput("right")
if input then
shell.run("dj", "play", "left")
term.clear()
term.setCursorPos(1,1)
print("Playing...")
sleep(5)
end
end

Would enjoy some help, thanks.

First when you declared the variable

side="right"

You never use it. This is not your problem, but it is unnecessary. Is there a noteblock you are trying to make a sound? Do you have a disk drive to your left? DJ needs a music disk to be loaded

Well, there are several things wrong with it. But I don't see any problems that would stop it from working, except for that infinite loop. Try this instead:

while true do
	term.clear()
	term.setCursorPos(1,1)
	print("Waiting...")
	os.pullEvent("redstone")
	shell.run("dj", "play", "left")
	term.clear()
	term.setCursorPos(1,1)
	print("Playing...")
	sleep(5)
end

That will wait until a redstone signal changes, start playing the disk, wait five seconds, then wait for the redstone signal to change again.

Yeah, I have a disk drive on the left side which I am trying to activate by stepping on a pressure plate. Im just kind of clueless when it comes to coding.

Much better! That worked! Thanks :)/>
