The document is a project report on a solar energy based automatic street light controller submitted by Amar Gupta, Manisha Bagani, and Varun Shah. It describes the controller's use of a 555 timer IC wired as a monostable multivibrator to automatically turn street lights on at dusk when detected by an LDR light sensor, and off at dawn. When dark, the LDR increases resistance to trigger the 555 IC and relay to power the lights from the solar panel energy storage. It saves around 40% of electricity costs compared to regular street lights.

2. PROBLEM STATEMENT Automatic switching of street lights considering the intensity of sunlight, brightness control of lights on detecting movement and error reporting to electric sub sections.
3. PROJECT SCOPE/OBJECTIVE Smart street light system tries to find solution for the faster depletion of energy resources due to the inefficient usage and wastage of these resources. Increasing electricity bill is something that can be witnessed by these practices. This project help to decrease the wastage of electricity by controlling the working of street light system that attributes to a good amount of electricity bills in our nation This project does not include methods to incorporate usage of renewable resources like solar energy.
4. DESIGN AND IMPLEMENTATION CONSTRAINTS Constraints are mainly in the module that regulate the brightness of the light by considering the traffic on the street at a specific time. Infrared proximity sensors are costly and at the same time maximum distance to which the sensor can sense is limited to 1 metre, which may not be sufficient for a 45 metre road.
5. DEVELOPMENT METHOD This project include three modules, the sunlight sensing and control of onoff of the lights, the traffic sensing and brightness control, error reporting system. Microcontroller used is arduino uno r3 atmega 328p ,which has to be programmed for the three tasks. Inputs for the same come from the three sensors.output include instruction to onoff the control sytems.

11. SYSTEM ARCHITECTURE
- The objective of this project is to make a smart solar panel which is follow the sun light. Solar panel converts sun light into electricity. It is eco-friendly and low-cost energy. But the solar panel is unable to move in front of the light source, hence solar panel not produces electricity of its full capacity. Solar panel is unable to move, it is fixed at one position. If we want full energy output from solar panel thenwe need to move manualy solar panel in front of the sun light

This report aims to let the reader understand the project work which I have done. A brief introduction to Solar Panel and Solar Tracker is explained in the Literature Research section. Basically the Solar Tracker is divided into two main categories, hardware and software. It is further subdivided into six main functionalities: Method of Tracker Mount, Drives, Sensors, Motors, Data Acquisition/Interface Card and Power Supply of the Solar Tracker is also explained and explored. The reader would then be brief with some analysis and perceptions of the information.
Project details - I have made a project Dual Axis Solar Tracker using Arduino to align the solar panel towards the higher density of Sun light. I have used a ATMEGA168 controller IC for programming, and two servo motor for movement of solar panel. It was now also available on EngineersGarage with the link- http://www.engineersgarage.com/contribution/how-to-make-a-solar-tracker. Check this out.
This system builds upon topics learned in this course. The aim of the project is to keep the
solar photovoltaic panel perpendicular to the sun throughout the year in order to make it more
efficient. The dual axis solar photovoltaic panel takes astronomical data as reference and the
tracking system has the capability to always point the solar array toward the sun and can be
installed in various regions with minor modifications. The vertical and horizontal motion of
the panel is obtained by taking altitude angle and azimuth angle as reference. The Arduino has
been used to control the position of DC servo motors. The mathematical simulation control
of dual axis solar tracking system ensures the point to point motion of the DC motors while
tracking the sun.

AUTOMATED LIGHT CONTROL SYSTEM FOR OFFICESDrm Kapoor
Electricity is one of the most important resources in this century that should be conserved. On several occasions, we get out of rooms, offices, hall and forget to turn off the lights/fan, thus the electricity is wasted and billing is also increased. Manual operation of light in offices is one of the challenges being faced by members of staff in any organization. This research work is focused on design and implementation of an automatic light controller used in offices in order conserve electricity as well as reducing electricity bill.. The major component used for the implementation of this research was Light Dependent Resistor (LDR) which works on the principle of changes in resistance of LDR according to light falling on it. This will ensure proper conservation of energy which reduces the cost of bill paying to IBDEC (Ibadan District Electricity Company). Manual application of controlling bulbs is eliminated by using this system. This automated system is not only applicable to offices but also applicable in, rooms, Hostels, Street lights, Garden lights, Hotels etc. Automatic light control requires less labor to operate since it works automatically therefore the running and opportunity cost is encouraging.
Solar Power Energy is a necessity for current time. We need to be aware with technology at all level. There is always a need to go for a substitute of electricity. Developing countries have to facilitate solar lights on road and provide a proper Research and Development sector for progress.
This latest electronics projects to build eBook contains many interesting and useful electronic circuit diagrams to build, each project is using low cost and easily available components.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

INTRODUCTION
Solar powered automatic street light controller is an very efficient device which
regulated the street light working. It automatically turns on when there is dark at
the dusk time and turns off at the dawn when the sun is out.
Solar powered automatic street light controller is one of the applications of
electronics to increase the facilities of life. The use of new electronic theories has
been put down by expertise to increase the facilities given by the existing
appliance. Here the facility of ordinary street light is increased by the making it
controlled automatically.
In Solar powered automatic street light controller there is a provision in which
the energy required to run the street light is provided by the solar energy.. In this
NE 555 IC is wired as Monostable multivibrator. For regulating the input AC
supply there is a regulator Section consisting of IC 7812. For detecting the light
the LDR is used as the sensor.

5. Solar energy based automatic street light controller
555 Timer IC
The 555 Timer IC is an integrated circuit (chip) implementing a
variety of timer and multivibrator applications. The IC was designed
and invented by Hans R. Camenzind. It was designed in 1970 and
introduced in 1971 by Signetics (later acquired by Philips). The
original name was the SE555/NE555 and was called "The IC Time
Machine". The 555 gets its name from the three 5-kohm resistors used
in typical early implementations. It is still in wide use, thanks to its
ease of use, low price and good stability. As of 2003, 1 billion units
are manufactured every year.
Depending on the manufacturer, it includes over 20 transistors, 2
diodes and 15 resistors on a silicon chip installed in an 8-pin mini
dual-in-line package (DIP-8).
The 556 is a 14-pin DIP that combines two 555s on a single chip.
The 558 is a 16-pin DIP that combines four slightly modified 555s on
a single chip (DIS & THR are connected internally, TR is falling edge
sensitive instead of level sensitive).
Chamelidevi Institute of Technology and Management
6. Solar energy based automatic street light controller
Also available are ultra-low power versions of the 555 such as the
7555 and TLC555. The 7555 requires slightly different wiring using
fewer external components and less power.
The 555 has three operating modes:
• Monostable mode: - In this mode, the 555 functions as a "one-shot".
Applications include timers; missing pulse detection, bounce free
switches, touch switches, Frequency Divider, Capacitance
Measurement, Pulse Width Modulation (PWM) etc.
• Astable Mode :- Also called as Free Running mode. The 555 can
operate as an oscillator. Uses include LED and lamp flashers, pulse
generation, logic clocks, tone generation, security alarms, pulse
position modulation, etc.
• Bistable mode or Schmitt trigger: - The 555 can operate as a flip-
flop, if the DIS pin is not connected and no capacitor is used. Uses
include bouncefree latched switches, etc.

SCHEMATIC PLAN
Light dependent resistor LDR is used as the light sensor. Its resistance increases
in absence of light while it decreases in present of light. NE 555 IC is wired as
monostable multivibrator. The trigger to this is signals from potential across 100k
resistor.
The 230 V AC is stepped down to 12 V by transformer (12V-0-12V). This 12V is
regulated by IC 7812 regulator to provide 12V. This 12V is supplied to the whole
circuit.
IC 7812 is used as the regulator IC which regulates the current and voltage to the
IC 555 and the rest of the circuit The output of IC 555 is used to drive a transistor
When the transistor conducts it operates the relay and controls the turn on and off
of the street light.
Chamelidevi Institute of Technology and Management
9. Solar energy based automatic street light controller
WORKING
The 230 V from AC mains is stepped down to 12V and Regulated by IC 7812.
This 12V is used for providing supply to the entire circuit. During the day time
condition, the presence of light decreases the resistance of the LDR So the
potential drop across the 100Kohm resistor increases so the voltage across the
trigger becomes greater than 1/3 of Vcc that is 4 volt so the output becomes zero
so the relay remains at off state so the light doesn’t turns off. In dark condition
like at night the resistance of the LDR increases so the potential drop across the
100k ohm resistor becomes less than 1/3 Vcc so the IC 555 is triggered and the
relay operates to turn on the street light . The solar panel of 12V provides a
potential of 12 volts to the circuit which operates upon the IC 555 and ultimately
controls the relay to regulate the street lights .This NE 555, which is wired as
Monostable multivibrator, is used to trigger the relay.
