Interfacing Servo Motor with PIC Microcontroller
Servo Motor uses error sensing negative feedback to control the precise angular position. Servos are used for precise positioning in robotic arms, legs, RC Aeroplanes, Helicopters etc. Please read the article Servo Motor for more information about its working and construction. Hobby Servo Motors have three wires, two of them (RED and BLACK) are used to given power and the third one is used to give control signals. Servo can be easily be controlled using microcontrollers using Pulse Width...
Servo Motor
Introduction
Servo Motors are ordinary geared down DC Motors equipped with servo mechanism for precise control of angular position. A servomechanism or servo refers to an error sensing negative feedback which is used to correct the performance of a device. Servos are used for precise positioning in robotic arms, legs, RC Aeroplanes, Helicopters etc. Servo Motors do not rotate continuously, their rotation is limited between fixed angles. Usually these motors have rotation limit from 90° to 180° and some special have limit 360° or more. An...
Interfacing Stepper Motor with PIC Microcontroller
Introduction
A Stepper Motor is a brushless, synchronous DC electric motor, which divides the full rotation into a number of equal steps. It finds great application in field of microcontrollers such as robotics. Please refer the article Stepper Motor or Step Motor for detailed information about working of stepper motor, types and modes of operation. Unipolar Motor is the most popular stepper motor among electronics hobbyist because of its ease of operation and availability. Here I...
Stepper Motor or Step Motor
Introduction to Stepper Motor
It is a brushless, synchronous DC electric motor, which divides the full rotation into a number of equal steps. It is also known as Step Motor. For example, in the case of a 200 step motor, one complete rotation (360°) is divided in to 200 steps, which means one step is equal to 1.8°. It can take only one step at a time and each steps are equal. The exact position of a stepper motor can be...
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...
