Hi everyone!
I want to built a fuel lavel indicator through a microcontroller system.
The fuel tank of the boat has a floater. The floater is connected on a potensiometer. My problem is how can i avoid the quick changes of the displayed level on the lcd which are cause from the sea's waves?
 

Re: fuel level

You need to filter the signal. Maybe an RC filter will do the job.
