UNITS

The ohm (symbol Ω) is the SI unit of electrical resistance named after Georg Simon Ohm Commonly used multiples and submultiples in electrical and electronic usage are the milliohm (1x10minus3) kilohm (1x103) and megohm (1x106)

CAPACITOR-

A capacitor (formerly known as condenser) is a passive electronic component consisting of a pair of conductors separated by adielectric (insulator) When there is a potential difference (voltage) across the conductors a static electric field develops in the dielectric that stores energy and produces a mechanical force between the conductors An ideal capacitor is characterized by a single constant value capacitance measured in farads This is the ratio of the electric charge on each conductor to the potential difference between them

Capacitors are widely used in electronic circuits for blocking direct current while

allowing alternating current to pass in filter networks for smoothing the output

of power supplies in the resonant circuits that tune radios to

particular frequencies and for many other purposes

The effect is greatest when there is a narrow separation between large areas of

conductor hence capacitor conductors are often called plates referring to an

early means of construction In practice the dielectric between the plates passes

a small amount of leakage current and also has an electric field strength limit

resulting in a breakdown voltage while the conductors and leads introduce an

undesired inductance and resistance

A light-emitting diode (LED) (pronounced ˌɛl iː ˈdiː [1] ) is a semiconductor light

source LEDs are used as indicator lamps in many devices and are increasingly

used for lighting Introduced as a practical electronic component in 1962[2] early

LEDs emitted low-intensity red light but modern versions are available across

the visible ultraviolet and infrared wavelengths with very high brightness

When a light-emitting diode is forward biased (switched on) electrons are able

to recombine with holes within the device releasing energy in the form

of photons This effect is called electroluminescence and the color of the light

(corresponding to the energy of the photon) is determined by the energy gap of

the semiconductor An LED is often small in area (less than 1 mm2) and

integrated optical components may be used to shape its radiation pattern[3] LEDs

present many advantages over incandescent light sources including lower

energy consumption longer lifetime improved robustness smaller size faster

switching and greater durability and reliability LEDs powerful enough for room

lighting are relatively expensive and require more precise current and heat

management than compact fluorescent lamp sources of comparable output

Light-emitting diodes are used in applications as diverse as replacements

for aviation lighting automotive lighting (particularly brake lamps turn signals

and indicators) as well as in traffic signals The compact size the possibility of

narrow bandwidth switching speed and extreme reliability of LEDs has allowed

new text and video displays and sensors to be developed while their high

switching rates are also useful in advanced communications

technology Infrared LEDs are also used in the remote control units of many

commercial products including televisions DVD players and other domestic

appliances

POWER SUPPLY

POWER SUPPLY-

This unit consist of rectifier filter amp regulator The rectifier unit is used to clip amp shift the input sine wave comming after the step down transformer The ndashve half cycle is shifted to the upper side amp filter unite provides the continuous output by the phenomenon of charging amp discharging the cap The regulator unit is used to give continuous regulated output as +5v for the power supply

RF Rx-

The job of the RF receiver is to demodulate the incoming modulated signal from the Antenna to recover the original bit stream as transmitted by the transmitter The serial data is further accumulated amp decoded for the output in the module itself

D-LATCH-

D-Latch is nothing but delayed latch initially is output is slow Whenever its clock input is triggered by the high going pulse its output toggles between the previous started value ie 1 to 0 and 0 to 1The next output is latched till the next trigger is applied to the clock input This output is given to the relay driving unit

RELAY DRIVER-

The relay driver is build arround the ULN 2004ICThis IC is nothing but push pull driver made up of darlington pair of transistors that can handle high voltage amp high current output load This is ideally suited suited for introducing between low level logic circuit multiple peripheral loads like relays

CONCLUSION-Reducing the number of remote controls in the living room is one of the challenges of the 21st century With this we can not only easily reduce the number of remotes we can also greatly increase the functionality robustness and ease-of-use of the remote controls that remain An IR remote control requires line-of-sight to the receiver making it difficult to operate from an adjacent room or many locations within the same room An RF remote control does not need line-of-sight That means you can hide your DVD player behind solid cabinet doors place the STB in the center of your house and stream the video to several TVs from there mute the music in your living room when you want to answer the phone in the kitchen and so much more In addition to being able to operate through doors and walls RF remotes have a much greater range than their IR counterparts often 90 feet or more

POWER SUPPLY-

This unit consist of rectifier filter amp regulator The rectifier unit is used to clip amp shift the input sine wave comming after the step down transformer The ndashve half cycle is shifted to the upper side amp filter unite provides the continuous output by the phenomenon of charging amp discharging the cap The regulator unit is used to give continuous regulated output as +5v for the power supply

RF Rx-

The job of the RF receiver is to demodulate the incoming modulated signal from the Antenna to recover the original bit stream as transmitted by the transmitter The serial data is further accumulated amp decoded for the output in the module itself

D-LATCH-

D-Latch is nothing but delayed latch initially is output is slow Whenever its clock input is triggered by the high going pulse its output toggles between the previous started value ie 1 to 0 and 0 to 1The next output is latched till the next trigger is applied to the clock input This output is given to the relay driving unit

RELAY DRIVER-

The relay driver is build arround the ULN 2004ICThis IC is nothing but push pull driver made up of darlington pair of transistors that can handle high voltage amp high current output load This is ideally suited suited for introducing between low level logic circuit multiple peripheral loads like relays

Here this is used to pull the relay coil to ground whenever its input is given high logic This helps to energise the relays and the device will remain ON till the input of IC ULN2004 is kept high
