Digital Voltmeter using PIC16F84A Microcotroller

Street project
Step-by-Step Guide
Beginner to pro

This tutorial is to help us on how to design, build, and code with Micro C, a digital Voltmeter using the PIC16F877A Microcontroller. This circuit is built to read the input voltage form the positive (+) and negative (-) terminals of the meter and display this reading unto the LCD(Liquid Crystal display)

In this project, you will need
  1. a PIC16F84A microcontroller.
  2. two capacitors and a crystal oscillator: used to produce an input clock frequency into the microcontroller
  3. 10K resistor and a pushbutton to reset Microcontroller when need.
  4. a 5V dc input voltage source
  5. Two street light LEDs
  6. Two 10K potentiometers: One to vary the LCD contrast and the other one to vary the measured volatge.
