3 Digit Digital Voltmeter Circuit Diagram. The complete digital voltmeter circuit diagram is shown in the above figure. Saved by arturs mekšs.
On the hardware part the pic16f676 has 10 bits 8 channels since most of pic microcontrollers has either 8 bit or 10 bit analog to digital converter module. Adjust vr1 to tune a correct voltage reading. The same principle applies to the dc voltmeter.
Then enter to the ac to dc converter circuit by ic1 and accessories in figure 3.
