Here is a new possible way of interfacing LCD with our controller other than what we have done earlier.
You can connect 8 data pins of LCD to any ports like PORT A/B/C/D. Since we are using Port A for ADC,it is not advisable to connect LCD there. In this particular schematics Pins 33 to 40 are connected to LCD ,but for our projects we will be connecting data pins of LCD on Port C ie. 7 pin on C0 and 14 on C7 and so on.

Interfacing LCD with At mega 16/32
Last time we have given example how to connect LCD with controller as you can see in following link. Now i am introducing concept of four wire data transmission.This way you will be able to save controller pin for another applications.
In above diagram you will see we are using 4 pin of PORTA for data transmission and another 3 pins of same PORT for control lines.In this way we are able to save pins and schematic drawing becomes much more easier.
Anyone who is using ADC for sensors should use other PORTB,C,D rather than PORTA(with same configuration).

LCD interfacing with Atmega 32/16
A device that produces rotational force is a motor. The very basic principal of functioning of an electrical motor lies on the fact that force is experienced in the direction perpendicular to magnetic field and the current, when field and electric current are made to interact with each other.

Motor Types-Introduction
This DC or Direct Current Motor works on the principal, when a current carrying conductor is placed in a magnetic field, it experiences a torque and has a tendency to move. This is known as motoring action. If the direction of electric current in the wire is reversed, the direction of rotation also reverses. When magnetic field and electric field interact they produce a mechanical force, and based on that the working principle of dc motor established.
The direction of rotation of a this motor is given by Fleming’s left hand rule, which states that if the index finger, middle finger and thumb of your left hand are extended mutually perpendicular to each other and if the index finger represents the direction of magnetic field, middle finger indicates the direction of electric current, then the thumb represents the direction in which force is experienced by the shaft of the dc motor.

Motor Types- DC Motor
An AC motor is an electric motor driven by an alternating current (AC).
It commonly consists of two basic parts, an outside stationary stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft that is given a torque by the rotating field.
There are two main types of AC motors, depending on the type of rotor used.
The speed of the AC motor is determined primarily by the frequency of the AC supply and the number of poles in the stator winding, according to the relation:
N_{s} = 120F/p
where
Ns = Synchronous speed, in revolutions per minute
F = AC power frequency
p = Number of poles per phase winding
Motor Types- Special Types of Motor
Iron less or core-less rotor motor- Nothing in the principle of any of the motors described above requires that the iron (steel) portions of the rotor actually rotate. If the soft magnetic material of the rotor is made in the form of a cylinder, then (except for the effect of hysteresis) torque is exerted only on the winding's of the electromagnets.
Axial rotor motor- A rather unusual motor design, the printed armature or pancake motor has the windings shaped as a disc running between arrays of high-flux magnets. The magnets are arranged in a circle facing the rotor with space in between to form an axial air gap. This design is commonly known as the pancake motor because of its extremely flat profile, although the technology has had many brand names since its inception, such as Servo Disc.
A servomotor is a rotary actuator that allows for precise control of angular position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors.
Applications of Servos
The Servo motors are used for precision positioning. They are used in robotic arms and legs, sensor scanners and in RC toys like RC helicopter, Airplanes and cars.
Servomotors are used in applications such as robotics, CNC machinery or automated manufacturing.

Operational Amplifiers circuit symbol is shown abovewhere:V+: non-inverting input V−: inverting input Vout: output VS+: positive power supply VS−: negative power supply Operation The amplifier's differential inputs consist of a non-inverting input (+) with voltage V+ and an inverting input (-) with voltage V−; ideally the op-amp amplifies only the difference in voltage between the two, which is called the differential input voltage.

There are effective ways to learn a a computer programming language in Visual Basic. You must know your own reasons for learning Visual Basic. If you're learning Visual Basic to achieve the ability to develop your own software then only going through books and online tutorials will not help you.
There are effective ways to learn a a computer programming language in Visual Basic. You must know your own reasons for learning Visual Basic.
Why are you learning Visual Basic?
What is your purpose. Be specific to yourself. Generally speaking, people learn computer programming languages so that they can develop their own systems or software applications to sell online to the people all over the world, or to companies or firms. Many people learn Visual Basic to get a job in a company where they have to work using Visual Basic. And some people learn Visual Basic for research work. There may even be other purposes.
