    THe project consists of 28 double digit numerical displays wired in series. They must be programmed to display 56 different numerical series. i.e., #1- 0-1-2-3-4-5-.... #2- 00-10-20-30-...#3- A combination of #1/#2, etc.

    The circuit must have a keypad or program selector with an alpha numerical display screen.
    Each LED module can be mounted on an individual board. Even though I took a couple of electronic classes in college, never had on hands experience.

    Can anyone help? :)

    By series I assume you mean they are driven by a serial data output. That many LEDs connected in series and your project would be humped :p

    This is a microcontroller project for sure. What is your level of experience? In electronics, microcontrollers, and programming?

    Cero Experience

    Hi Bob, Thanks for your reply. I have no experience at all. Took General Electronics class, (Ohms law, series and parallel circuits, resistors, capacitors, etc.) however, I have never had on hands experience or written an schematic diagram. Can supply detailed explanations and lay out of desired array.

    Regards,

    Robert

    Clarification

    I do not understand the term "humped". However, the LED's are attached to one another to form a single string and are driven by a microcontroller. Can supply additional data.

    Regards,

    I assume that you mean the the microcontroller will connect to the first display board, and it will connect to the next etc.

    The key would be designing the 2 digit display that you would then be replicating 28 times. How far are they going to be apart? This would affect how the data would be communicated.

    Once you have a design for the displays and their interconnection, you could probably get away with buying a microctroller demo board with keypad and display then the programming it to accept the patterns and send out the the data to the displays.

    Can I ask what is the purpose of this project?
