Everyone knows that PIC microcontrollers are still very popular due to its cheap price, user friendly, simple package, and its uncounted applications. One of the major application of PIC16F676 is its internal 10-bit ADC(analog to digital converter), this option helps us to convert our analog data in to digital format in a easy way. In this project we use PIC16F676 microcontroller to design a 30 v DC meter. After successful completion of this project you would be able to use this panel in various systems to measure its output or input voltage. Everything is clear in Schematic diagram. Do a proper wiring for 7 segment LCD. You can easily adjust its accuarcy by changing a values of 47K resistor and 10k trim pot.
