As the name implies, the purpose of having a notice board is to pass notice to the public or passerby of the particular place it is been placed or mounted. Notice board is a surface intended for the posting of public messages, for example, to advertise items wanted or for sale, announce events, or provide information. This notice board is made of a light emitting diode, or they can be placed on the road or public places so people can other people to read and see.
LED notice board uses lighting as a means of conveying their information. Light-emitting diode (LED) is highly used because it is way of way to increase visibility.

1.1 INTRODUCTION
Notice board is a surface intended for the posting of public messages, for example, to advertise items wanted or for sale, announce events, or provide information. This notice board is made of a light emitting diode, or they can be placed on the road or public places so people can other people to read and see.
Light-emitting diode (LED) technology is frequently used in signs. This technology, first used primarily at sporting events, later appeared at businesses, churches, schools, and government buildings.
Signs frequently use lighting as a means of conveying their information. Light-emitting diode (LED) is highly use because it is way of way to increase visibility. LED fluoresces and scatters the light. The light transmission through the markers creates a bright and colorful display. LED's commonly have a half-life (to 1/2 brightness) of 50,000 hours.
LED notice board features various flashing effects that are sure to attract the attention of passersby. The flashing pattern as well as the displayed colors can be cycled with these restaurant signs. These illuminated displays could be hung on any glass surface with the use of some simple suction cups. All of the LED writing boards sold here include wall screws and anchors as well as nylon rope to hang from the overhead. Use these flashing write-on signs as an advertising medium in a restaurant or nightclub. Bar owners choose these LED writing boards to announce live bands appearing throughout the week, or to list the featured drink specials. The framing on these advertising signs are solid metal with a black painted finish. The profile on these LED writing boards is one inch deep, thereby conforming to ADA requirements for items mounted on a wall. Choose one of these restaurants signs today for your café or coffee shop.
These LED sign board is the ideal neon board for growing revenue and customer base. This illuminated restaurant sign is a great way to customize advertising messages for your store, hotel, casino lounge or other business. These LED writing boards feature a clear acrylic covering that is easily cleaned. Use a wet-erase marker to create your own customized fluorescent board. This LED sign board, also known as an advertising signs, feature small lights running the perimeter of the black frame. When this illuminated signage is turned on, these lights make your graphics glow, as if under a black light. These LED writing boards also have the capability to be illuminated with no blinking lights. These illuminated menu signs will certainly attract attention of patrons. This LED sign board looks best in dimly lit settings such as bars, night clubs and restaurants. The lighting technology in these menu displays is quite advanced. This LED sign board feature bright, equally distributed lighting so that even the center of the unit is bright. There are no hot and cold spots on any of these restaurant menu displays. Additionally, with these LED writing boards there is never any need to worry about light bulbs being blown. The technology on these menu signs uses diodes as the primary source of light.
1.2 PURPOSE OF THE PROJECT
The main purpose of signboard is communication, to convey information such that its receiver can make cognitive decisions based on the information provided. In general, signage can be classified into the following functions: (a)Information: signs giving information about services and facilities, e.g., maps, directories, instructions for use, etc. (b)Direction: signs leading to services, facilities, functional spaces and key areas, e.g., sign posts, directional arrows, etc. (c)Identification: signs indicating services and facilities, e.g., room names & numbers, toilet signs, number of floors, etc. (d)Safety and Regulatory: signs giving warning or safety instructions, e.g., warning signs, traffic signs, exit signs, rules & regulations.
1.3 OBJECTIVE OF THE PROJECT
This main objective of this work is to construct an electronics device that can be used to pass information to the public or passerby using light emitting diodes.
1.4 SIGNIFICANCE OF THE PROJECT
The LED sign board is very slim and lightweight in design. LED light source, lower power consumption. Ultra slim & ultra light. Top designs for show window and guide board. This LED sign board is ideal for advertising or displaying purpose. The sign board allows you to display your advertising messages, product images at prominent places.
1.5 APPLICATIONS AND ADVANTAGES
This project can be used public places as well as hospitals and private companies, schools, colleges and universities.
Notice boards are particularly prevalent at universities. They are used by many sports groups and extracurricular groups and anything from local shops to official notices. Dormitory corridors, well-trafficked hallways, lobbies, and freestanding kiosks often have Notice boards attached to facilitate the posting of notices.
1.6 LIMITATION OF THE PROJECT
Presently almost all electronic notice boards are designed using wired system. One of the drawbacks of the design is the system is inflexible in term of placement, that is the information placed cannot changed easily and the wiring can be messy.
1.7 PROJECT WORK ORGANISATION
The various stages involved in the development of this project have been properly put into five chapters to enhance comprehensive and concise reading. In this project thesis, the project is organized sequentially as follows:
Chapter one of this work is on the introduction to an electronics notice board using LED. In this chapter, the background, significance, objective limitation and problem of an electronics notice board using LED were discussed.
Chapter two is on literature review of an electronics notice board using LED. In this chapter, all the literature pertaining to this work was reviewed.
Chapter three is on design methodology. In this chapter all the method involved during the design and construction were discussed.
Chapter four is on testing analysis. All testing that result accurate functionality was analyzed.
Chapter five is on conclusion, recommendation and references.
This material is a complete and well researched project material strictly for academic purposes, which has been approved by different Lecturers from different higher institutions. We make abstract and chapter one visible for everyone.
