5.1 Code Overview
LED MOVING MESSAGES displays:-
Light emitting diodes are advan- tageous due to their smaller size, low current consumption and catchy colours they emit.An LED message display sign provides more space to display your led moving message in one line. 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 BetaBrite’s WYSIWYG software and your PC, or by using the infrared remote keyboard (software, RS232 9-pin serial port cables and infrared keyboard included). 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 as shown in the 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. LED signs deliver high impact advertising. Displays are available in single line scrolling signs, two and three line boards, electronic billboards, true color large video walls and stock tickers.

LCD Message Display :-
This LCD message display can show text with large characters on an 20*4 LCD module. The display can show five characters at a time. Each characters is build from twelve characters of the display module. The text on the display can be read from up to ten meters distance.
The data to build each character is stored in an external 24C32 serial EEPROM which has 4096 bytes of memory. The characters that can be shown on the display are: A to Z and 0 to 9. There are in total 35 characters so we need 35*12 bytes = 420 bytes. The text is also stored in the EEPROM.
It is also possible to show the time and temperature on the display.

Hello Sir,
ReplyDeleteMy name is Hawra Bohra and i am final year biomedical engineering student from D.Y Patil University in Navi Mumbai.Our project is designing of Hyperbaric Oxygen Therapy Instrument (HBOT).In this we have used an acrylic chamber where the patient is kept and he is supplied with pure oxygen at the fixed pressure above normal atmospheric pressure.We have used pressure sensor to sense the pressure and reference pressure is set.We are planning to use microcontroller to control the pressure in the chamber by comparing the sensor pressure and the reference pressure set.Also we are using safety valves for patient safety. I am facing the problem as to how can i program the microcontroller 8051 to control the pressure in chamber and safety valve opening.
Sir i would request you to please help me with these problems and also with the electronic circuit.Thank You.

Hello sir i am a 4th year student of k.j.somaiya coll of engg and i am building a project which makes use of sms through a modem to display the message on the lcd and i want the code for 89c51 for the same.Plz can u send the code for the above mentioned projeact?Plz reply asap....my mail id is dimagger@gmail.com
ReplyDeleteI am a 4th year student of k.j.somaiya coll of engg and i am building a project which makes use of sms to display a message on lcd screen thru a modem and 89c51.Plz this is my earnest request to all the ppl out there to send me a microprocessor code regarding the same....my email add is dimagger@gmail.com
ReplyDelete@ Darshak :-
ReplyDeleteSend me your circuit diagram and project proposal. If you have proteus ISIS , then make the circuit diagram in it. if you have written some code sofar then send me this also, so that i shoud start work from where you feel difficulty.
zip the code and circuit diagram files and then send me.
my e-mail is given on this blog (left side below the counter).
Hello sir Darshak here and thank you for replying to my comment on http://microcontroller51.blogspot.com/2011/05/moving-message-display-using-atmel.html link.
ReplyDeleteSir, i still haven't started the programing but i am sending you the circuit diagram in the doc file and a pdf file regarding my project. I myself have only this much of information.
Plz sir i would really appreciate it if you could help me with my programming.My project is due May 2012 and i have just started with the hardware.
@ Darshak :-
ReplyDeleteYou have enough time to work on this project. So you should work hard to understand the different fields of your project like the programming, simulaion, troubleshooting and hardware development.
Thus i advise you to install proteus isis software on your computer and try to make your circuit in it. It is a very good tool which will help you to test your circuit and program on PC without any compoenets fixing and actual hardware.
The circuit diagram in proteus isis is also required by me for your project as i also use it to debug any code for microcontroller and test on PC.
Thats why i ask every student to make a circuit diagram of their project in proteus isis, otherwise it has to be draw by me. and i have not enough time to waiste on each project.
i think you understand it.
hey friend i want to display the name in scrolling of lcd 16*2..

Jey (scrolling text message on LCD using 8051) :-
ReplyDeleteHere in this post you will find complete information about the moving message diaply regarding complte report on MMD, circuit diagram MMD and coding for moving message display. This post is for scrolling text on LCD using microcontroller 8051. I hope you will find your desired information, if you feel any dificulty plz ask.
sir
ReplyDeleteplz send me the project information of moving message display on LED's with 8051 microcontroller on my id priyajangra1993@gmail.com
@ Priya (Moving Message Display):-
ReplyDeleteWhat Kind of information you want reqarding the moving message display project.
I think, all information related to Moving message display is already uploaded on this blog including circuit diagram, code, reports, comments.
What else you want, instead that you should tell me in what area you need help and you should share information regarding your project, what you wnt to do, what will be your circuit diagram and how you will write your code.
hi sir this ruchit patel.
ReplyDeletem final year student. i want report on the LCD moving msg display using solar energy. so if u have any kind of material related to it than send me on my id ruchit8364@gmail.com.
sir, i m finsl yr student frm GEC BHARATPUR,i m building a project on moving messege on lcd so send me plz its code regrding 8051 microcontroller
ReplyDeleteplz send me moving messege display code for lcd...
ReplyDeleteHello sir,
ReplyDeletei have dropped you a mail regarding my project and it would be really appreciated if you could check it out A.S.A.P.You had askd me to mail you the code which i have done and to implement it on proteus which is not possible as we have gsm modem in our project.
hello sir,
ReplyDeletewe are developing "GSM based diaplay board" with moving message on LED board.In the circuit we used 16*2 LCD, microconroller AT89C51 and the board is serially interfaced with a GSM modem. The modem is receiving the message and displaying on computer when seen in hyper terminal. but when serially interfaced to circuit board no message is being diaplayed on 16*2 LCD.
Please kindly provide us with the complete code for this project as much early as possible.. Please mail the code to the below mail id..
sira0458@gmail.com
Please help me out sir.. thanking you sir..
