Matrix Keypad

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...

Interfacing Matrix Keypad with PIC Microcontroller

This tutorial explains 'What is a Matrix Keypad ?' and 'How to Interface Matrix Keypad with PIC Microcontroller ?'. Matrix Keypad Matrix Keypad is a very useful and userfriendly when we want to design certain applications like Calculator, Telephone etc. Matrix Keypad is made by arranging push button switches in rows and columns. Just imagine, if you want to interface a 4*4 (16 keys) matrix keypad with a microcontroller.  In the straight forward way, you will need 16 pins of a microcontroller for that, but...

Interfacing DC Motor with PIC Microcontroller using L293D

This tutorial explains " How to interface DC Motor with PIC Microcontroller ? ". DC Motor and L293D We can't drive a DC Motor (depends) directly with a Microcontroller, as DC Motors requires high current and high voltage than a Microcontroller can handle. Microcontrollers usually operates at +5 or +3.3V supply and it I/O pin can provide only up to 25mA current. Commonly used DC Motors requires 12V supply and 300mA current, moreover interfacing DC Motors directly with Microcontrollers may affect the...

DS1307 RTC

Interfacing Real Time Clock (RTC) DS1307 with PIC Microcontroller

DS1307 is a low power serial real time clock with full binary coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM (Non Volatile Static Random Access Memory). Data and Address are transferred serially through a bidirectional I2C bus. The RTC provides year, month, date, hour, minute and second information. The end date of months is automatically adjusted for months fewer than 31 days including leap year compensation up to year 2100. It can operate either in 24-hour format or 12-hour format with...

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...

Analog to Digital Converter (ADC) in PIC Microcontroller

ADC module of PIC microcontroller have usually 5 input for 28 pin devices and 8 inputs for 40 pin devices. The conversion of analog signal to PIC ADC module results in corresponding 10 bit digital number. PIC ADC module has software selectable high and low voltage reference input to some combination of VDD, VSS, RA2 and RA3. In the following example project we will convert analog input to channel 1 to 10 bit digital number with low voltage reference (Vref-) 0v and high...

LCD interfacing with PIC Microcontroller – MikroC

A PIC Microcontroller can  be easily made to communicate with LCD by using the built in Libraries of MikroC. Interfacing between PIC and LCD can be 4-bit or 8-bit. The difference between 4-bit and 8-bit is how data are send to the LCD. In the 8-bit mode to write an 8-bit character to the LCD module, ASCII data is send through the data lines DB0- DB7 and data strobe is given through the E line. But 4-bit mode uses only 4 data lines. In this mode the...

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...
