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 [...]

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 [...]

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 [...]

Push Button Switch

Using Push Button Switch with PIC Microcontroller

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. In this tutorial we use a push button switch, when we press on it an LED glows for a second. Push [...]

LED Chaser using PIC Microcontroller

LED Chaser is a simple project for beginners that can build using PIC microcontroller. In this 8 LED are running like a Ring Counter. It is very simple and you can create different patterns as you like just by modifying the MikroC program. Here I am using PIC16F877A, one of the most popular PIC microcontroller. This tutorial is on the assumption that, you have basic knowledge in mikroC and Proteus. If you haven't please go to this tutorial. MikroC Code void main() { [...]

Blinking LED using PIC Microcontroller – MikroC

Welcome to the world of PIC Microcontrollers. You are in the right place if you are a beginner in the filed of microcontrollers. MikroC is the best compiler for beginners as it contains built in functions for most of the commonly used tasks. But MikroC is less efficient and the hex file generated will be large size compared to other compilers. So I suggest you to use Hi-Tech C compiler by Microchip after you get familiar with microcontrollers. Note [...]
