We have provide a list of best mini projects for engineering students. This list gives a basic idea about how to choose and what type of projects that we may choose in final year engineering. Student have to use their innovative ideas to do the projects individually.
Position your glass of water on a table and then place the mirror inside it at an angle. Make sure that the room is completely dark. Close all the curtains and the blinds so it gets pitch dark. Take the flashlight or your torch and aim the light towards the mirror that you placed inside the glass. Watch a rainbow appear from the angle of your mirror. Adjust the angle of the mirror.
You have just made your own rainbow, but do you know the explanation behind your creation? A rainbow is an optical phenomenon that appears as a band of colours in an arc, resulting from the refraction of the sun's light rays by the rain. When the sun shines on the droplets of water in the atmosphere, a rainbow, as people see it, is formed.A rainbow displays the colours red, orange, yellow, green, blue, indigo and violet in respective order. Its formation can be caused by other things as well just like mist, dew and spray. To explain it further, when light strikes the surface of a water drop, it changes speed thus causing it to bend. It is refracted as it enters the water and then refracts again as it leaves the droplet. The outcome is light being reflected in varying angles, creating a rainbow.Light travels in varying waves where the length of each would depend upon the colour. When light retracts, the different colours refract and bend in different amounts as well. This is the reason why we see different colours in a spectrum when there is a rainbow
For a working couple, it is hard to find time to have laundry day where the cloth is dried through the whole day because the weather can change from sunny to rainy days. This paper use Microcontroller PIC16F877A to install all programs that will give instructions to conduct this system properly. This paper will introduce the techniques which will automatically retrieve-out the clothes when it is the sunny day and oppositely retrieve-in the clothes when it is a rainy day. This part needs DC motor to convert electrical power into mechanical power for retrieve-out and retrieve-in all the clothes. Temperature sensors that will be used here can measure temperature and day condition whether it is sunny or rainy day more accurately. LDR (Light Dependent Resistor) sensors will be used to detect light intensity. Rain detector will be used to sense when it begins to rain outside by detecting rain water from moisture impedance sensor locate at the rod. The dry-time of the clothes will be setup using rotary knob switch and it will automatically retrieve-in the clothes using DC motor when the dried-time is finished. Here we will display the day condition, temperature and dry-timer using LCD (Liquid Crystal Display) or indicator light such as LED (Light Emitting Diode).
Now-a-days water scarcity has become a serious problem in India and there are many factors responsible for this like improper supply of water from the dam, improper water saving systems, etc. but one major factor is the improper opening and closing of the dam gate according to the level of water in the dam. Also till date the control mechanism of the dam gates is done manually and using microcontroller. But there are lots of errors in manual method. Also the controller based system is huge and hence suitable for major dams due to its cost. For medium and small dams like irrigation dams does not require such huge controller systems. So to reduce these problems a mechatronic control system is proposed in this paper. This project is a AT89S51 microcontroller based dam gate control system which helps in keeping an eye on the frequent usage of water resources from dam for irrigation purposes and efficient operation of dam gate according to the level of water and also helps in indicating about flood to people living in the surrounding. This proposed mechanism of dam gate control reduces the water wastage and efficient usage of available water is ensured. Also there are heavy load shedding problems in the villages in almost all states of India. To overcome these problems the proposed dam gate control system can be combined with the operation of the geothermal and nuclear power plants for generation of electricity.
This project aims at designing and executing the advanced development in embedded systems for energy saving of street lights. Nowadays, human has become too busy, and is unable to find time even to switch the lights wherever not necessary. The present system is like, the street lights will be switched on in the evening before the sun sets and they are switched off the next day morning after there is sufficient light on the roads. This project gives the best solution for electrical power wastage. Also the manual operation of the lighting system is completely eliminated. In this project the two sensors are used which are Light Dependent Resistor LDR sensor to indicate a day/night time and the photoelectric sensors to detect the movement on the street. To control the street light system, Finally, the system has been successfully designed and implemented as prototype system.
The main aim of this project is to design a system to open/close mobile platforms in between the train tracks for elder or handicapped people.In Railway stations normally we use bridges to go to the other platforms. Sometimes it is very difficult for the elderly persons or handicapped persons to use that bridge. this project finds a good solution. Mainly the tracking of a train is controlled by switches, this is used for automatically close/open the mobile platform. Rocker switches are placed to control the bridge open/close.
The development of a country depends on the village’s development. As part of the smart village concept, we need a system that helps in development of villages in the areas like Primary education, people’s healthcare,Roads and Transportation,Drinking water facilities ,government policies awareness and availability of basic facilities/infrastructure.This system helps the members to collaborate, plan, assess and implement different activities.
