What is the difference between Induction, Inductors & Inductance?
Induction
Current is produced in a conductor when it is moved through a magnetic field because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. This process of generating current in a conductor by placing the conductor in a changing magnetic field is called induction.
Inductor:
An electrical device (typically a conducting coil) that introduces inductance into a circuit. E.g choke
Inductors introduce Inductance.
Inductance
The property of a circuit or circuit element that opposes a change in current flow, thus causing current changes to lag behind voltage changes. It is measured in henrys
Mutual Inductance
A measure of the relation between the change of current flow in one circuit to the electric potential generated in another by mutual induction. Like inductance, mutual inductance is measured in henries.
Self Inductance:
The property of an electric circuit or component that caused an emf to be generated in it as a result of a change in the current flowing through the circuit.
Induced EMF :
A voltage is induced when a conductor cuts magnetic field lines or when the magnetic field through a coil changes. This is called induced e.m.f.
Impedance:
The total opposition that a circuit offers to the flow of alternating current or any other varying current at a particular frequency. It is a combination of resistance R and reactance X, measured in ohms.
What are Amplifiers & what is the difference b/w Transistors & Amplifier
Amplifier is a group of components used to increase level of an electrical wave. One of the components may be a transistor, a vacuum tube or a magnetic amplifier.
AMPLIFIER TYPES:
Class A:
100% of the input signal is used
CLASS B:
50% OF INPUT IS USED
CLASS C:
LESS THAN 50 %
CLASS AB:
Somewhere between Class A and Class B.

Visual Basic & Electronics [22 April 2011]
Visual Basic is a great developers language it allows you to create applications that are very functional and to do so in a quick way. This is why i love VB6.
Visual Basic (VB) is the third-generation event-driven programming language and integrated development environment (IDE) from Microsoft for its COM programming model. Visual Basic is very easy to learn and use. We can develop our own applications and can use them for different purposes. We can also do serial communication with help of VB.
See how this vb application communicates with the LED Display in this video.

Latest Microcontrollers
Microcontroller can be termed as a single on chip computer which includes number of peripherals like RAM, EEPROM, Timers etc., required to do some predefined task. All the below mentioned Microcontrollers are equally good, it depends on the type of project we are working with and which will suit our project better.
The Intel 8051 microcontroller is one of the most popular general purpose microcontrollers in use today
PIC is a family of Harvard architecture microcontrollers made by Microchip Technology
AVR was developed in the year 1996 by Atmel Corporation. They
are fast microcontrollers. The architecture of AVR was developed
by Alf-Egil Bogen and Vegard Wollan. AVR derives its name from
its developers and stands for Alf-Egil Bogen Vegard Wollan RISC
microcontroller, also known as Advanced Virtual RISC.
AVR microcontrollers are basically of 3 types:
1. TinyAVR – Less memory, small size, suitable only for easy applications
2. MegaAVR – These are the most popular ones having good
amount of memory (upto 256 KB), higher number of inbuilt
peripherals and suitable for moderate to complex applications.
3. XmegaAVR – Used commercially for complex applications, which require large program memory and high speed.
32 bit RISC

Microcontrollers vs Microprocessors
Microcontrollers and Microprocessors are used as controlling components in all types of modern electronic devices. Most people think controllers and processors are a same thing but that's not the case.
Microprocessor is the central processing unit
in a computer. Microprocessor will require lots
of other ICs around it (like ROM, RAM and
timers). Microprocessors are used to handle a
set of tasks that control one or more external
events or systems. The computer you are using to
read this webpage uses a microprocessor to do
its work.
Microcontroller is like a computer inside a
single chip. A microcontroller has all necessary
parts (CPU, ROM, RAM, timers) integrated inside
one IC unlike microprocessor.
