ABSTRACT:
The circuit is built around binary counter CD4060 (IC2), which has a built-in oscillator
and 14 cascaded bistable multivibrators. The oscillator generates clock pulses based on
the values of resistors R3 and R4 and capacitor C3.
For the given values, Q13 output of IC2 goes high after 30 seconds of power-on. Resistor
R2 resets the IC for proper operation. The output of IC2 is fed to the gate of the SCR via
resistor R6 and LED2, which function as a voltage dropper as well as output status
indicator.
When the SCR gets gate drive, it fires to energise relay RL1. The latching function of the SCR
keeps the relay energised until the power to the circuit is switched off using switch S1. When the
relay energises, its normally closed (N/C) contacts break and light turns off.
The back-up white-LED lamp comprising LED3 and LED4 gives ample light in the event of
mains failure. It is powered by a 9V rechargeable battery, which is charged at around 200mA
current via diode D6 and resistor R7 when the circuit is switched on.

ABSTRACT:
The light operated lamp switch project needs no manual operation of switching ON and OFF.
The system itself detects whether there is need for light or not. When darkness rises to a certain value
then automatically light is switched ON and when there is other source of light, the light gets OFF.
At day time resistance of the LDR low, the transistor Q1 conducting and Q2 will conduct and
gives positive trigger to the 555 IC. This results LED does not glow. When darkness falls the resistance
of LDR increases this makes the transistor Q1 OFF and Q2 conduct and turn on the 555 IC and make the
LED is glow.
By employing this circuit energy consumption can be reducing considerably as the switches ON
or OFF automatically in appropriate time. Moreover, errors which occur due to manual operation also
can be eliminated completely. It can be used for other purposes like garden lighting balcony lighting etc.

ABSTRACT:
This project SMART GLOVE for DEAF and DUMB, mainly works as an interpreter,
converts hand gestures into text or voice or in commands. The SMART GLOVE needs to be
worn on the hand by the disabled and depending on the variation of the movements, the device
will convert it intelligently into voice and in a text. This message will be out from the speaker
and LCD display. The smart glove senses the movements through the flex sensors which pick up
the gesture made by the individual and then with the help of Arduino, that analog input is
converted into digital for various gestures. For every particular gesture there is specific digital
output and that digital output for specific gesture is reserved for specific message. So, when the
individuals do that particular gesture, the predefined message for that gesture is displayed on the
LCD along with word sound through speaker and that specific message is also transmitted in the
form of text or call with the help of GSM module to the various registered numbers.

ABSTRACT:
In day-to-day life, there are a number of water dispensers for providing drinking water. Such as in homes,
collages, offices and many other places. These dispensers are managed manually by a person, where a
person checks each of the dispensers individually and accordingly manages it. In order to fulfill
the drinking water and adjust the water temperature requirement a number of dispensers are placed
throughout the building. Thus, their management has become difficult. The purpose of technology
is to make our life easier. Therefore, with the advantage of technologies like Internet of Things (IOT)
we can change the way we do things in a better way. The management of water dispensers becomes smart
and easy using Internet of Things. In this project, the main concentration is to manage the water level and
water temperature. For that the project design as one Peltier system based digital water dispenser system
has been proposed NodeMCU will be used to control Peltier module for temperature control and water
management. One digital display unit will be adding to display total control unit. Also, in addition one
NodeMCU based water temperature will be implemented with the help of temperature sensors. And by
cloud computing IOT (Internet of things) will be helpful to adjust the temperature required. The
NodeMCU will have synchronized the temperature adjusted by cloud computing and controlling the
water temperature on tank. The technology Internet of Things (IOT) is an advanced and efficient solution
for connecting the things to the internet and to connect the entire world of things in a network. Here things
might be whatever like electronic devices, sensors and automotive electronic equipment’s. The system
deals with monitoring and controlling the environmental conditions like temperature, relative humidity,
light intensity and CO level with sensors and sends the information to the webserver page and then plot
the sensor data as graphical statistics. The data updated from the implemented system can be accessible
in the internet from anywhere in the world. Lastly, the main goal of the proposed system is to monitor the
water levels, water temperature and manage overall dispensers. It will provide faster, easier and cost
effective management. It also includes the design of monitoring system with advantages of low cost and
accuracy.
