Hi I'm trying to build a timer to see the time it takes for an object to pass form one sensor to another. For this to work I need to know how to set up timer then getting that time to be displyed on an LCD screen. I am out of my depth on this one, any help would be welcomed with open arms.

Have a look at the pulseIn command

Mem;

How would you use the pulseIn command? It sounds like he has two seperate sensors, a start and stop sugnal.
