This is a circuit for dual channel voltmeter. This circuit is based on PIC microcontroller. This is the figure of the circuit;
PIC voltmeter can measure 0-70 Volts which should be more than enough for most of electronic projects providing excellent reading accuracy and resolution. It has two input channels for measuring two voltage sources at the same time. This PIC voltmeter project uses PIC16F876 microcontroller with built-in ADC (Analog to Digital Converter) and 2x16 back lighted LCD display.
