Interfacing EEPROM with PIC Microcontroller

What is an EEPROM ? EEPROM is an abbreviation for Electrically Erasable  Programmable Read Only Memory and it is a Non-Volatile memory. It is used in computers and other electronic devices to store data that must me saved during no power supply. EEPROM is a class of ROM (Read Only Memory) which can be electrically erased in bit by bit and able to store new data. A small amount of EEPROM (usually 128/256 bytes) is available internally with PIC Microcontrollers. I have already posted about Using...

Matrix Keypad

Interfacing Matrix Keypad with PIC Microcontroller using MikroC Library

I already posted about Interfacing Matrix Keypad with PIC Microcontroller with some user-defined functions. Advantages in using user-defined functions are we can extend it up to any number of keys and able to customise according to our application. The MikroC Pro for PIC Microcontrollers provides a library for working with 4*4 keypad. It can also be used to interface 4*3, 4*2 and 4*1 keypads. MikroC provides the following three functions to interface Matrix Keypad. Keypad_Init Keypad_Key_Press Keypad_Key_Click Keypad_Init Prototype: void Keypad_Init(void); It initializes a particular port for working with keypad. A global...

Reading Multiple Pressed Keys from Matrix Keypad using PIC Microcontroller

I have already post about Interfacing Matrix Keypad with PIC Microcontroller. I suggest to read that article before reading this. In some applications it may require to scan more than one key at a time. Reading Multiple Pressed Keys from Matrix Keypad is not simple as reading Single key. We want to change the program as well as the circuit of matrix keypad for reading multiple keys. The main problem is unexpected shorts may come to act when we press more...

Multiplexing of Seven Segment Displays with PIC Microcontroller

When a Seven Segment Display is interface with PIC Microcontroller it needs minimum 7 pins to display a value. But real time applications like Digital Clock, Calculator, Digital Watch requires 3-6 seven segment displays. Lets assume that we need 6 digit display, ie we need 7 segment * 6 Display = 42 pins. Thus we actually need Microcontroller with 42 output pins. This is waste and not economical to use lot of pins of a Microcontroller just for display. The simplest way...

Voltmeter

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...

Water Level Indicator and Controller using PIC Microcontroller

Here is a simple, versatile project which indicates the level of water and automatically controls it by using PIC Microcontroller. The Water Level Sensing Section senses the level of water in the tank and sends it (wireless) to the Receiver Section. Receiver Section is connected to the Controlling Section, which process the received information and produces visual, sound indications and controls the operation of the motor whenever required. The project is divide into 4 sections. 1. Power Supply Section Power Supply section provides required supply for Receiver...

Push Button Switch

Using Push Button Switch with PIC Microcontroller

Introduction This article is meant for beginners in the field of microcontrollers. When I started with microcontrollers, as everyone I also need to learn how to interface a switch with microcontroller. Here we use PIC Microcontroller 16F877A and MikroC Pro compiler. This tutorial assumes you have basic knowledge about programming PIC Microcontroller, else you read the article Blinking LED using PIC Microcontroller. Push to On Switch Push to Off Switch In this tutorial we use a push button switch, when we press on it an LED...
