Voltmeter and Ammeter can be easily made using PIC Microcontroller having ADC (Analog to Digital Converter). I am using PIC16F877A and the result is displayed on an LCD Display. PIC16F877A is enough if you do this project only for testing purposes....
The large scale integrated circuit has a built-in filter to reject AC interference. Input resistance of 11 megohms (11 million ohms) yields potentiometer quality voltage readings, and digital readout eliminates interpolation of voltages. This small, lightweight instrument needs...
Powered by two "AA" penlight cells, the Model CPV-2 requires no push to read switch, and the solid state integrated circuit has built-in filter to reject AC interference. Input resistance of 10 megohms (10 million ohms) of this instrument results in potentiometer quality voltage...
