Circuit Explanation
   IR emits the rays amplified by transistor and generated by
    555 timer.
   TSOP sense the signal and sends to the transistor Which has
    555 timer sends to the microcontroller will has the
    programming which sends to decoder which trigger the relay
    Through which it will trigger the relay ON.
   Certain frequency and ignores all other IR received.
   The best frequency for the job is between 30 and 60kHz, the
    most used is around 36kHz.
   So, remote controls use the 36kHz (or around) to transmit
    information.
     InfraRed light emitted by IR Diodes is pulsated at 36
    thousand times per second, when transmitting logic level "1"
    and silence for "0".
   To generate a 36kHz pulsating infrared is quite easy, more
    difficult is to receive and identify this frequency.
   This is why some companies produce infrared receives, that
    contains the filters, decoding circuits and the output shaper, that
    delivers a square wave, meaning the existence or not of the
    36kHz incoming pulsating infrared.
   When switch S1 is in „on‟ position, the transmitter circuit, IR
    receiver module TSOP1738, which is commonly used in colors
    televisions for sensing the IR signals transmitted from the TV
    remote, is used as the sensor.
   IR signals transmitted from the TV remote, is used as the sensor.
    The IR beams transmitted by IR LED1 and LED2 fall on infrared
    receiver module IR RX1 of the receiver circuit to produce a low
    output at its pin 2. This keeps transistor T1 in non-conduction
    mode. Now when anyone enters through the gate to interrupt the
    IR beam, the IR receiver module produces a high output at its pin
    3.
IR TRANSMITTER
   IC 555 is used as an Multivibrator.
   This is a free running oscillator and the frequency can be
    adjusted using 100k preset (variable resistor).
   Free running oscillator means, it is itself starting circuit which
    outputs a waveform that repeats itself without being either
    triggered or re-triggered.
   The output of the oscillator is periodic (i.e. repeats itself
    regularly) pulse or wave train.
   In a periodic signal the wave repeats itself indefinitely until the
    circuit is either turned off or otherwise inhibited.
   In this mode of operation, the capacitor charges and
    discharges between 1/3 Vcc and 2/3 Vcc.
   As in the triggered mode, the charge and discharge times and
    therefore the frequency are independent of the supply
    voltage.
IR RECEIVER CIRCUIT
   when IR signals does not falls on the TSOP 1738 its output pin
    no.3 goes high.
   R14 resistance is used to limit the current at the output of the
    TSOP and fed to pin1 of the NOT gate ic which has internal 6 not
    gate.
   1st not gate invert its output and its output is again inverted by
    another not gate and increases its output current to switch the
    switching transistor 2N2222A or SL100 which is NPN switching
    transistor.
   The ground signal is generated by the transistor is fed.
   Receiver circuit operated at 5V DC and it is drive from power
    supply circuit.
   Transformer converts 230V AC to 12V AC and the 12V AC is
    converted into DC by Diode D1 & D2 it filtered by Capacitor
    C1, IC3 gives.
   Regulated 5V DC to other circuit. Infra-red receiver module
    detected 38 kHz signal this is transmitted from transmitter circuit.
MICROCONTROLLER
   Microcontrollers are used in automatically controlled products
    and devices, such as automobile engine control systems,
    remote controls, office machines, appliances, power tools,
    and toys.
   By reducing the size and cost compared to a design that uses
    a separate microprocessor, memory, and input/output
    devices, microcontrollers make it economical to digitally
    control even more devices and processes.
   Mixed signal microcontrollers are common, integrating analog
    components needed to control non-digital electronic systems.
   The Light control of street is very crucial especially in
    applications where precision are of importance.
   This work investigates and implements a microcontroller-
    based adjustable system for a energy.
INFRARED IN ELECTRONICS

   Infra-Red is interesting, because it is easily generated and
    doesn't suffer electromagnetic interference, so it is nicely
    used to communication and control, but it is not perfect, some
    other light emissions could contains infrared as well, and that
    can interfere in this communication.
   The adventure of using lots of infra-red in TV/VCR remote
    controls and other applications, brought infra-red diodes
    (emitter and receivers) at very low cost at the market.
   This light can means something to the receiver, the "on or off"
    radiation can transmit different meanings.
   Lots of things can generate infrared, anything that radiate
    heat do it, including out body, lamps, stove, oven, friction your
    hands together, even the hot water at the faucet.
DIGITAL CONTROL

   Efficient control of motor and other electrical devices
    becomes critical where high precision, accuracy, flexibility;
    reliability and faster response are of paramount importance.
   Therefore for efficient control electronics and digital control
    are employed in which a solid state semiconductor are used.
   In advance we can use a software programming in which
    electronics circuit are interfaced with computers.
   By using software program there is less possibility of
    irregularity.
Advantages of Digital Control

   Digital control gives the high precision and accuracy.

   Digital control gives better speed regulation.

   Digital control gives faster response and flexibility.

   It gives better time response and improved performance.

   It has easy software control.

   It is economical and reliable.

   The greatest advantages of digital control is that by changing the program desired
    control technique can be implemented without any change in the hardware
BLOCK DIAGRAM OF POWER
SUPPLY
POWER SUPPLY
   Power supply is the first and most important part of our project.
   In the proposed project the power supply circuit is used to provide
    the regulated supply to the IC`s used in the project.
   Power supply circuit consists of step down transformer, rectifier
    circuit, filter circuit and regulator IC.


    Step Down Transformer
o    Transformers are static device which convert the electrical energy
    from one circuit to another circuit without any change in frequency
    and power.
o   Step down transformer means the transformer which reduces the
    supply voltage to the desired value.
o   In our project we need 12 volt DC supply, therefore in this project 12-
    0-12, 500mA transformer is used.
Rectifier Circuit
o   Rectifier is a circuit which converts the AC electrical energy into Dc electrical
    energy.
o    For operating of semiconductor devices used in this project we need
    regulated DC supply.
o    In this project we use centre tap full wave rectifier.
o    Full wave rectifier circuit is capable of converting sinusoidal input into a
    unidirectional output.
o   The circuit diagram is as shown in the figure.

Filter Circuit
o   It is seen that the output of the rectifier is not pure DC, because it contain
    some amount of AC component which is called as ripple factor.
o   This circuit is connected after the rectifier circuit. In our project capacitor input
    filter is used.
o   The circuit is as shown in the figure.
                     The capacitor is connected in parallel to minimize the ripple
    factor.
Regulator Circuit
o        In our project for the operation of IC we need +5 volt regulated
    supply is necessary therefore a voltage regulator circuit is used.
o    A voltage regulator is a circuit that supplies constant voltages
    regardless of change in the load current. IC voltage regulators are
    versatile and generally used.
o   The 7800 series consist of three terminal positive voltage
    regulators. These ICs are designed as fixed voltage regulator and
    adequate heat sink.
o    It can be deliver output current in access of 1A.
o   These devices do not required external component.
o    These ICs has internal terminal overload protection and internal
    short circuit and current limiting protection.
