  PIC16F877A based volt meter  This post provides a simple digital voltmeter circuit  using PIC16f877A microcontroller. This code is written in C language using MPLAB X IDE with XC8 compiler.  In this post, it is assumed that you know, How to use ADC of PIC16F877A microcontroller.  How to interface LCD with PIC16F877A microcontroller.  Figure 1.   Digital voltmeter using PIC16F877A In this circuit PORTB pins are used to interface LCD with PIC167877A microcontroller . The input to the digital voltmeter is given on the RA0 (or AN0) pin. You cannot feed a 20V signal directly to a PIC microcontroller’s input channel. It is too higher than its operating voltage, and the microcontroller could be damaged. So, first we need a voltage scaler that will scale down the input voltage to the safe operating voltage range of PIC16F877A. It can be achieved by a simple resistor divider network shown in the below Image. Figure:2 Voltage div...
