The Low Pin Count USB Development Kit provides an easy, low cost way to evaluate the functionality of Microchip's PIC18F14K50 and PIC18F13K50 20-pin USB microcontrollers. Kit contains the hardware, software, and code examples. This is what i would use if i have to make a Quick USB Voltmeter or Ammeter.
If you want to do such a project, use Opto-Isolation for High-Energy circuits for Safety. The Analog Value from Attenuator, Shunt, Current Transformer is amplified and converted to frequency then thru opto-coupler reaches uC. This protects PC and User.Be very careful in High Voltage and High Current. Use proper transducers and Isolation to Protect man and machine.
