Summary of ATMEGA128 MMC CARD SUPPORTED 3-COLORS LED SIGN MESSAGE BOARD
This project details a custom 3-color LED marquee built around the ATmega128 microcontroller. Unlike commercial signs lacking programming interfaces, this design uses an MMC card to store text messages and features serial port communication for uploading content. It supports five distinct scrolling speeds, offering a flexible solution for displaying dynamic data like temperature or humidity within home automation networks.
Parts used in the ATMEGA128 MMC Card Supported 3-Colors LED Sign Message Board:
- ATmega128 microcontroller

ATmega128 microcontroller based on the ATmega128 a quality marquee project instead of text information stored on the MMC card codes shared resources
At the beginning this project was to buy a led sign to interface with my home automation network. This automation network display information like temperature wind speed, humidity etc I had bought on LED Sign but when I received it I got a surprise! There was no serial port to program messages
3 Colors messages
5 Scrolling speed
Serial port for uploading messages

- What is the primary purpose of this project?
To create a quality marquee project that stores text information on an MMC card instead of relying on pre-programmed codes. - Why was this custom board developed?
The developer bought an LED sign but found it lacked a serial port to program messages for their home automation network. - Can this system display multiple colors?
Yes, the project supports 3-color messages. - How many scrolling speed options are available?
The system offers 5 different scrolling speeds. - How are messages uploaded to the device?
Messages are uploaded via a serial port connection. - What kind of information can the automation network display?
The network can display information such as temperature, wind speed, and humidity. - Where is the text information stored?
Text information is stored on the MMC card. - Does this project support home automation integration?
Yes, the project was designed to interface with a home automation network.
