Im completley new to op amps and alike.

I am making a project where i need to measure about 5/6 different pressure levels using an op amp and force guage.

I am using this so i can detect the amount of liquid remaining in a bottle.(10%, 25% 50%75%100%)
My aim is to eventual display the level on the LCD. if it drops below 10% then stop a switch from being activated.

Im am using a Pic 16F628


I noticed the mention of tut above?


Any help you could give me would be much appreciated


cheers
