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...

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...

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...

USB PIC Programmer : PICKit2

Microchip's PICKit2 is much more comfortable,reliable and powerful than the other programmers that we can find all over internet. It is a USB based ICSP (In Circuit Serial Programming) programmer. Since it is a first release, Microchip published all the resources of PICKit2 public, which includes hardware schematics and all source code of softwares used. Through this any one can add features, fix bugs and modify source code. Documents and other supporting files of PICKit2 are available at Microchip's Website. We have simplified...

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 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() { ...
