hello everyone ! I would like to ask you guys if someone could help me compiling this code to be able to use a LED when the flow meter's signal is null .. in other words, when there is no water passing through . Also What boot should i use? I have arduino one r3 and i need to make it run without PC…

Activating LED on signal input=null

Please post the complete code.

I can see at least 3 conditions even in that unhelpful fragment. Which one is "this condition"?

Steve
