my Project is SMS based notice board in which
there is an wireless notice board which is connected to GSM MODEM wid the help of microcontroller and Max232 IC
I have to display the notice on LED Display board

SO i wants Circuit diagram of that..
 

Re: Sms based notice board

LED Matrix is of 5*16

and ya just like that video but microcontroller is ATMEGA8L of atmel..
 

can be any other but atmega8l is best for this project.
 

This is schematic

This is video https://www.youtube.com/watch?v=CuD3jrj-_EI
Don't ask for coding because that is your job.
 
Hello sir
in this schematic there is no connection between microcontroller and Max 232 IC.
and
can we use AT89c51rd2 or AT89c52 microcontroller or atmega8l Plz

There is connection microcontroller to MAX232 in pin 25 and 26.
 
But sir is their any schematic diagram in which ATmega8L is used wid LED display.??

Better use ATMEGA8A-AU its 16MHz and atmega8L is 8MHz both are TQFP32, also A-AU is cheaper.

Hello sir,
Can we use AT89c51 or AT89c52 or p89c52 ??
so if yes then please give me the complete schematic diagram of SMS based notice board wid any display(LCD or LED).
