In this project we are building a basic and low cost frequency counter circuit . It can measure from 16Hz to 100Hz signals with a maximum amplitude of 15V. The sensitivity is high, the resolution is 0.01Hz. The input signal can be a sine, a square or a triangle waveform. The counter can be used …
PIC microcontrollers ( Programmable Interface Controllers), are electronic circuits that can be programmed to carry out a vast range of tasks. They can be programmed to be timers or to control a production line and much more. They are found in most electronic devices such as alarm systems, computer control systems, phones, in fact almost …

Here is a simple tutorial on how to receive serial data from PC(Personal Computer) Hyperterminal and display it on 16×2 lcd using PIC16f877 microcontroller. Its not much difficult you just need to know how to use USART(Universal Syncronous-Asyncronous receiver transmitter) of PIC 16f877. Serial data is transmitted and recived by PC using DB-9 OR DB-25 …
Attendance in colleges is generally paper based which may sometimes cause errors. Taking attendance manually consumes more time. So the proposed attendance system uses RFID technology to take attendance. In this system, each student is issued an RFID tag. Controlling unit is in the institute. Whenever the card is placed near the reader, it will …

This post provides the implementation of free running counter ( using c language ) for PIC16F84A micro-controller. This code is written in such a way that, the counter starts from a value of ‘0’ ( displayed on the seven segment ) and then increments this value after every second. So, the seven segment display starts …

Alphanumeric LCD displays have become very popular for microcontroller applications because they can add a lot to a project in a variety of different ways. A text message giving the user instructions as well as feedback can make the application seem much more “professional” and easy to use. I like to use LCD’s to help …
In this tutorial we will see How to interface a 16×2 character LCD Module with PIC 16F877A Microcontroller using CCS C Compiler. 16×2 character LCD is a very commonly used LCD module in electronic projects and products. 16×2 means it can display 2 rows of 16 characters. It is a very basic and low cost …
