In this video, we'll understand the basics of servo motors, and see how to connect a servo motor with Arduino Uno, to control the servo motor movements. we will also break inside the servo to check its different parts and its working.

Stepper motors fall somewhere in between a regular DC motor and a servo motor. They have the advantage that they can be positioned accurately, moved forward or backwards one 'step' at a time, but they can also rotate continuously.

Stepper motor is brushless DC motor, which can be rotated in small angles, these angles are called steps. Generally stepper motor use 200 steps to complete 360 degree rotation, means its rotate 1.8 degree per step. Stepper motor used in many devices which needs precise rotational movement like robots, antennas, hard drives etc.

LED interfacing is the first thing, one would try to do while getting started with any microcontroller. So here in this tutorial we are going to interface a LED with 8051 microcontroller, and will write a C Program to blink the LED. We have used a very popular microcontroller AT89S52, of 8051 family, by ATMEL.

Keypads are widely used input devices being used in various electronics and embedded projects. They are used to take inputs in the form of numbers and albhabets, and feed the same into system for further processing. In this tutorial we are going to interface a 4x4 matrix keypad with 8051 microcontroller.

Seven segment displays are important display units in Electronics and widely used to display numbers from 0 to 9. It can also display some character alphabets like A,B,C,H,F,E etc. In this tutorial, we are going to learn how to interface a segment with 8051 microcontroller. We are using AT89S52 microcontroller.

One of the most popular stepper motor among students and makers is the 28-BYJ48 Stepper Motors. These motors are used in your DVD drives, Motion camera and many more place. It has a 4 coil unipolar arrangement and each coil is rated for +5V hence it is relatively easy to control with any basic microcontrollers.

This dual bidirectional motor driver is based on the very popular L298 Dual H-Bridge Motor Driver IC. This module will allow you to easily and independently control two motors of up to 2A each in both directions.

The L293D is a famous 16-Pin Motor Driver IC. As the name suggests it is mainly used to drive motors. A single L293D IC is capable of running two DC motors at the same time; also the direction of these two motors can be controlled independently.
