Hi
Just wondering whether anyone could help with a piece of code which basically triggers LEDs and note on a loudspeaker when LRDS(switches) hi or low. I wanted to add an LCD screen in to display a message however when i add the code for this is messes with the exsisting code and the sound makes a horrible sound.
I have added into the loop() but not sure whether it should go here or within the setup()
