Introduction:
Microcontroller based digital advertisement display using LED /LCD is a kind of process in which the ad or information is going to be output on LCD/LED.
This project is an implementation to provide interfacing and manipulative control of a HD44 compatible liquid crystal display using ATMEL 89c51 microcontroller. Moving message display using 8051 microcontroller. System in which the digital data status can be monitored and controlled on system. This system allows user to monitor the status of LCD. Now a day’s every where we can find the usage of LCD/LED hence the data communication will be of higher success rate by reaching most of the targeted users.
Objective and Scope:
The objective of this project is to design and develop the microcontroller based digital advertisement display using LCD/LED. Light emitting diodes are advantageous due to their smaller size, low current consumption and catchy colors they emit. Brighter and multi-color LED’s are available, to give your moving message signs maximum impact. Advertise your daily specials, new products and services. Announce upcoming events at a moment’s notice. Welcome VIPS, guests or important customers with impact. Promote employee safety, quality and health awareness programs. Within minutes you will be creating dynamic messages using the software and your PC, or by using the infrared remote keyboard (software, RS232 9-pin serial port cables and infrared keyboard included). LED signs deliver high impact advertising. Displays are available in single line scrolling signs, two and three line boards, electronic billiboards, true color large video walls and stock tickers. In this project the prototype is getting developed to demonstrate the working model of the above mentioned system. Thereby acquiring the hands on experience of building microcontroller based system and involve in the programming of microcontroller.
Scope of the project is to design the required hardware and develop the
control application (software) to create demo version of the product.
Proposed Project Work:
There are following major components involved in developing the digital advertise
1) Computer Serial port: Interfaces between microcontroller and system for data. System in which the digital data status can be monitored and controlled on system. This system allows user to monitor the status of LCD.
2) Microcontroller: The main system of our project to digital advertise display using LCD/LED. Which communicates to LCD and computer through serial cable. The 89C51 microcontroller accepts string input from the desktop computer through parallel port interface between 89C51 microcontroller and desktop and display the string passed by the desktop user to the LCD display.
3) LCD: An LED message display sign provides more space to display your led moving message in one line. The software is able to display ASCII characters on the LCD display and also provides the additional and attractive feature of moving the display string in a unidirectional manner. The display can be fixed on a veroboard of suitable size and connected to ground of a common supply (of 6V to 9V) while the anodes of LEDs are to be connected to emitters of transistors T1 through T7 circuit. LED Signs can be controlled from a central location by using a PC running Windows message software and data transmitter with receivers for wireless display network.
