If Detection Help.

I am going to be producing a Food Market with a computer. I wanted to know how to set up an if statement to when someone presses a button.
It would be nice to have it detect based on the Red Power Color.

So Ya I am new to the detection system……so I am playing around with it.

For this, you will need to use a loop for it to constantly check for the redstone signal

while true do
    os.pullEvent("redstone") -- so it only continues when a redstone event is trigger and it will act as a yield
    if rs.testBundledInput("side", colours.red) then -- so if the colours.red part of the bundled cable is ON
        --code
    else
        --code when it's not
    end
end

You can test multiple colours with if..elseif..elseif..end

if .. then

elseif .. then

elseif .. then

end

Would it be possible to use OR in this case ex.

while true do
  os.pullEvent("redstone")
  if rs.testBundledInput("side", colours.red) or rs.testBundledInput("side", colors.blue) then
    --code if it's red or blue
  elseif rs.testBundledInput("side", colours.green) then 
    --code if it's green
  else
    --code when it's neither
  end
end

It would be possible but aren't you detecting a certain color? Or you want [said code] to run if the red OR blue cable is on? Which in that case it would be alright to use an OR statement. Also I wish you the best of luck with your Food Market ;)/>

EDIT: You will however have to change the rs.testBundledInput("side",colors.red) Since "side" is not a valid side unless you define a variable like so:

Side = "[Side the cable is on]" –This must be in the form of a string -> " "
–code

Then call the variable like so:
rs.testBundledInput(side,colors.red)

It would indeed work
