Voltmeter and Ammeter using PIC Microcontroller
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. I suggest to use PIC with low pin numbers and multiplexed 7 segment display if you wish to use this as your measuring instrument. Prerequisite If you don't know the basis of PIC ADC and LCD Interfacing please read the following...
