Very nice. PIC16F877A and any other are widely using these days. You can easily find for your project. You can try digital door lock with password, techometer, robotic hand, dotmatrix led scrolling display, anemometer reading, voice recognition, etc..
I am using HT1632C in one of my company project. I am using 8 holtek IC driven by its internal RC osc. Their is no problem in fixed display strings. But in case of scrolling display the characters are getting double width and uneven flickering is observed in the edges. Please give me the idea why it is so. (...)
Hi, It seems to be a cliche to ask code help for scrolling display. But, mostly the help is available for scrolling led display or Char LCD display. I am using 128x64 GLCD on which we write data using column scanning. So, scrolling of (...)
Hello!!! I have to display the scrolling message on to the led Matrix.. I have to connect 4-led Matrix. I am using 74HC595 Serial to Parallel Converter. Firstly i am checking only single matrix:- Here is my circuit diagram 81938 I display ARUN SHARMA in scrolling (...)
I once wrote a scrolling text code for 8 dot-matrix displays in assembler. It shouldn't be hard to implement it in C. You may start

Please use 'google' to search instead of posting it here : scrolling Text led display you want it for free? If so no one is going to give you as it is a fast moving product. I advise you to start doing it yourself. You will get help here when you face problems.
Hello, To make scrolling display, everywhere I see a technique of led matrix i.e. rows x columns. But, as the number of leds increases, the hardware becomes costly. I am in search of a solution which would be cheap in terms of hardware and flexible enough to add number of leds. I am ready to design (...)
