Voltage monitor for car battery

use an op-amp set up has a devider you can then put upto 20v in and get 0-5v out and for safety tie a 5V zener diode to prevent damage to the pic or just a resistor devider

I personal use op-amp has i can measure up to 60V

Thanks for the advice! Could you be specific with regard to where the 5V zenere diode must be placed. (I'm rather new to electronics!)

THANKS!
