Hey all,
 

My goal (not a contest project) is to build a nifty Bench Power Supply using an old Desktop PC power supply, an SX and three of Bean's HC4LED displays (these are kool!) to show acutal 12vdc, 5vdc and amps.  

 

I think I understand the concept of how to measure the voltage but how do I measure the amps (say up to 5 amps) and supply that info to the SX so that it can update the digital displays and a send the status out a serial port?  I need something like a "shunt" but how do I get the info into the SX?
