you are better off just wiring in your DVM meter in it's current measurement mode and monitor
Sorry if I was unclear, it's more of a weak desire rather than a curiosity. I'm building a user interface on my computer that will be showing live stats from my robot. Voltage, temperature, position, etc, I am interested in adding current measurement to that list. I'm looking to send the data to a PC, so using a multimeter wouldn't be adequate since it only displays the info on the device rather than outputting it in any way I can use.
I'm looking through the docs on the ACS712 and Parallax's breakout board for it - at first glance this device seems to be limited to measuring current on 5V supplies. I'm using a 12V
battery and then using three 5V regulators to power different parts of my robot. While it would be a bit costly, I could get three chips to measure the three regulators, but there are also a few components that feed directly off of the 12V, meaning I'd still be missing some of the current draw for the whole system.
BTW that link to the ZMC10D-ND doesn't seem to work.http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=ZMC10D-ND
I'm rather hesitant to work shunt resistors and soldering wires to pins, partly because it involves multiple parts (I was hoping there would be a single component solution to this problem) and partly because I lack a soldering gun at present, but could acquire one if no other solution is viable
