    hello everybody
    i learnt from the forum that it is probably easiest to implement a LED
    bargraph by means of an LM39xx... However, are there some manufacturers
    that offer a broad range of LED-line designs? for example the number of
    LEDs, the size and shape of LEDs, the colours and so on?
    thanks a lot for your advise..
    have a good day.

    For hobbyist use the choice may be a bit more limited (though you can build
    your own bar in discrete leds of many shapes, sizes & colours).

    Some 2-20 led bar modules
    http://www.rapidelectronics.co.uk/rkmain.asp?PAGEID=80008 and they'll all
    stack for longer bars.

    Note there are other bargraph ICs as shown on the page, a lot cheaper than a
    3914/5/6 if you only want a 5-high..
