Can I pick someone's brain please?
I'm at the moment trying to make an auto switchover gadget to change from running on Diesel to Veg Oil once certain temperatures have been reached, and to try and work this out I'm using the easypic5 development board.
So far: I have a 16f877A programmed so it will switch certain outputs when certain inputs go high all and well
It even displays what it's doing on the LCD display

What I'd like to incorporate if its possible is this? or a variation of it the Bargraph but use it as a fuel level sensor, i.e. changing position depending on the level of the fuel in the tank (variable resistor)

Does anyone know any code that will do that or give me a starting place to play with?
I know I've got 2 A/D converter inputs on the developement board I can play with that have a 10K pot connected and are configured so I can change the input on either of the RA0, RA1, RA2, RA3, RA4, or RA5 pins and measure the voltage on them ( unfortunatly I'm only just learning about Pic's at the moment and know nothing about A/D and how to use it, I am learning by trying and experimenting But I am a quick learner), so IF anyone has any code they could share with me to show me how to get started with this I'd be grateful Thanks
