Q. Where can I get more circuit designs, for projects for my bs2p ?

Archiver

Hi, I want very much to build a device with my bs2p24 & demo
board, which will take a voltage from a car's battery and
display it by either lighting an LED, or on the LCD
display.

I realize that would be a rather involved circuit, but
I've scoured the Parallax and Stamps in Class sites, and
I don't see anything there. Also, I picked up a copy of
Nuts/Volts, and nothing there either.

Can the basic stamp handle something like taking a
12 - 15v reading, from a car battery ?

Thanks,
Jim

Look at voltage controlled ocsillators, build one then use pulsin on
the stamp to give you a freq reading which would correspond to a
certain voltage.

Wouldn't a simple voltage divider work ?

then one could use an ADC or possibly some form of RC to get pulses
that coorosponded to the voltage ?
