Ampere meter in basicstamp module NEED HELP

indigo2

i've just finished my stampworks. |In de book there was a experiment 28 that shows an voltmeter in the basic stamp module,

does anybody knows how to hook up a ampere meter to the basic stamp module?

i've searched for an digital ampere meter and this is what i found:

but i need to read it in my basic stamp module, som like this


if amperes (r1 >= 0)·then

begin
···· program
end

can someone help me please?
so instead of reading voltage i want to read amperes

thank you

A digital ammeter is a voltmeter that measures the voltage across a low value resistor called a "shunt resistor". Download and read the "Basic Analog and Digital" tutorial (www.parallax.com/tabid/535/Default.aspx) which shows how to use an Analog to Digital Converter with a Stamp to measure voltage. The circuit you showed has the shunt resistor and other input circuitry for what is essentially an analog to digital converter, just designed for driving a display directly rather than providing the data to a Stamp.

Thank you very much, i'll dive into the shunt resister, and let you know if it worked. [noparse];)[/noparse]
