Green Technology
What is Green
Technology?
As the name shows green technology is one that has a "green" purpose. By green we do
not mean the color, however, Mother Nature is quite green, and the long and
short term impact an invention has on the environment is what we are talking
about. Green inventions are environmentally friendly inventions that often
involve:...
Circuit Breakers.....
How Circuit Breakers Work:
The simplest circuit protection device is the fuse.
A fuse is just a thin wire,
enclosed in a casing, that
plugs into the circuit. When a circuit is closed, all
charge flows through the fuse wire -- the fuse
experiences the same current as any other point
along...

Three Phase Transformer
The basic principle of a three phase
transformer is shown in the Fig
The three cores are arranged at 120o from each other. Only primary windings are
show on the cores for simplicity. The primaries are connected to the three
phase supply. The primaries carry the currents IR, IY and IB producing...
WHAT IS MASH
What is Mesh
suppose
you have an electric source such as a dry battery cell, an LED and two pieces
of conducting wire. If you want to make the LED to glow, the positive terminal
of the battery must be connected with one lead of LED by means of one
conducting wire and in same way the negative terminal of the battery must be
connected to other lead...

RELAY
"What is A Relay"
A relay is an electrically operated switch. Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits),...

stepper motor projects
A stepper motor (or step motor) is a brushless DC electric motor
that divides a full rotation into a number of equal steps. The motor's
position can then be commanded to move and hold at one of these steps
without any feedback sensor (an open-loop controller), as long as the motor is carefully sized to the application.
Switched reluctance motors...
servo motor projects
his is a simple project where we are going to interface the servo motor
with PIC microcontroller. The microcontroller we are using in this
project is PIC 18f452. Its not a much difficult project and is just for
understanding of servo motor. Servos can
start to sink a lot of current like any motors so it is wise to be
sure
that your batteries....
serial-port-complete-tutorial
in this tutorial we are gonna cover all about serial port and their
interfacing with micro-controller . If you guys feeling any problem then
ask in the comments and I will try my best o satisfy you and I am
giving you surity that if you be with me in all steps then you will be
able to use serial port quite easily. Following are the list which...
SINGLE PHASE INDUCTION MOTOR SPEED CONTROLLER,
— The main objective of our Project is to
build a speed control circuit for induction motor to control the speed of the
induction motor using a feedback system for either on load or off load
conditions. Speed control will be achieved by a microcontroller and input will
be given through a keypad from stand still to rated...
