LED dot matrix scrolling message – 14×5 – source code

I have built various scrolling message badges for instance using the 16F57- 10×5 and 12×5. However, since these chips only have a small FLASH, there is not much flexibility. I don’t really recommend these controllers for a scrolling message. Recently I have started a new project, using small 1.9mm ready made modules, and a 16F884. It has 4K FLASH which is sufficient (about 1/3 are used), and 256 bytes RAM. ...

LED Scrolling Display Project Working With Circuit Diagram

We normally use a simple static LED display screen to convey a message. Earlier, when we want to display large data, we used to change message for every few instances. Now scrolling displays are more preferred to static. By using a pre programmed controller, we can make LED display in scrolling way. We can also make LED to adoptable by using PC controller based system. Simple Outdoor LED Message Moving or S ...
