    Hi all


    check please this project

    http://sohilp.blogspot.com/2011/10/tutorial-10x8-led-matrix-arduino.html

    i liked it but the problem is my teacher doesn't want me to work with Arduino . she said try to find like this project " Matrix LED" but by using
    parallel port + db25 + microprocessor

    i want to ask you what Material will i need ?

    i have to submit the report tmw :(

    help me please :(:(

    :) thank you

    i get answer from someone
    he said
    Probably yes. You'll need to know how much current/voltage parallel can source or sink. I'm sure it is in the range of arduino, but may be +-12V. Check!

    Serial is another option. Again, it'll probably be RS232 at +-12V. You can get RS232 to TTL converters though, and a serial to parallel chip. That'll let you control your LEDs via a serial port.

    how can i make the new circle with this option
    I asked this person but i didn't get any answer yet:confused::confused:

    Parallel port is deprecated for years.

    Have a look this: http://pic.hitechworld.org/data/ledmatrixtag

    The source code is included.

    The program is built in a way the matrix size is independent from the scrolling. The image is at first built inside RAM.

    It can be modified for different number of LEDs.
    It should be possible to change for different PICs, and for different controllers. The PIC dependent code is all isolated so you only need to change that.

    If you use my code, feel free to link to the URL.

    Microprocessor could be anything.

    A microcontroller is a microprocessor, only the RAM + EPROM is built into the chip. And microprocessor are very expensive and difficult to work with.

    There are not many microprocessor LED matrix circuits on the internet.

    An Arduino is an ordinary microcontroller by the way.

    :(:confused:
    I wanted to project the idea close to the idea of the first project
    Be used LED and microprosser
    And the Circle clear it:confused::mad::(
