This PIC Voltmeter Amperemeter was designed to measure output voltage of 0-70V with 100mV resolution and 0-10A current with 10mA resolution. It is a perfect addition to any DIY laboratory power supply, battery chargers and other electronic projects where voltage and current consumption must be monitored. The heart of the meter is PIC16F876A microcontroller with built-in analog to digital converters and 2x16 green backlighted LCD display. Circuit design uses very few external components making it possible to fit this handy meter on a small PCB.
