Interfacing Servo Motor with PIC Microcontroller – MPLAB XC8

Servo Motor Servo Motor is an ordinary geared dc motor equipped with closed loop servo mechanism which uses position feedback to control exact angular position of the rotor. These are commonly used in robotic arms, legs etc. Servo Motors do not rotate continuously, their rotation is limited to fixed angles. Usually these motors have rotation limit from 90º to 180° and some special have limits 360° or more. Servo Motors usually have three wires. RED and BLACK wires are used to provide...

Interfacing LCD with PIC Microcontroller – MPLAB XC8

In this tutorial we will see How to Interface a 16x2 character LCD module with PIC 16F877A Microcontroller using MPLAB X IDE and MPLAB XC8 C Compiler. 16x2 Character LCD is a very basic and low cost LCD module which is commonly used in electronic products and projects. 16x2 means it contains 2 rows that can display 16 characters. Its other variants such as 16x1 and 16x4 are also available in the market. In these displays, each character is displayed...

Compensated Attenuator

An attenuator is an electronic device which reduces the power or amplitude of a signal without considerably affecting the wave shape. Thus it works in an opposite way that of an amplifier does. Attenuator provides loss (gain < 1) while an amplifier provides gain (gain > 1). A Compensated Attenuator is a simple two port network which provides a constant attenuation over a wide range of frequencies. Here I am explaining attenuators and compensation in the input of vertical deflection amplifiers used...

Using Push Button Switch – MPLAB XC8

Push Button Switch I hope that you already go through the first tutorial of MPLAB XC8, Getting Started with MPLAB XC8 - LED Blinking. In that tutorial we learn how to use an output pin by driving an LED. In this we will learn how to read an Input pin using a push button switch. We already seen that TRIS register is used to set direction of each IO pin, ie Input or Output and PORT register is used to read...

Read Modify Write Problem with Mid-Range PIC Microcontrollers

RMW Problem with PIC 16F Family Microchip's mid-range PIC Microcontrollers use a sequence of operations : Read, Modify and Write to change output state of a pin. In certain circumstances RMW operations might cause unexpected behavior of outputs. You might have already experienced this issue and struggled with it as you can't find exact reason with microcontrollers unexpected behavior. Mid-Range PIC Microcontroller uses two registers, TRIS and PORT to control the direction and status of an IO pin respectively. When you try...
