Hello everyone

I want to drive the OEM fuel gauge used on most common vehicles. Current
gauges use a resistive device to ground to drive the gauge, for example most
Chevy use a 0-90 ohm sender ( 0=full, 90=empty) , Ford 160-10 or 70-0 ohm and
a few others.How can I use a stamp or PIC to drive these gauges. I was
wondering if I could use PWM to drive the gauge to ground? I could utilize a
different table for each vehicle type. Any suggestions on how I might
accomplish this. Feel free to offer other suggestions I don't know if PWM will
work, but I am sure someone out there has figured out a slick way to do this.

         Gauge----------------Sender-----------GND

Thanks in advance
