I am wondering what Arduino might be able to run a series of 3mm leds that will indicate one of TEN Points on a layout(0-9). Some will have 8 leds, others will have up to 14, each Number(0-9) will be ON at one at a time.
From ITS OWN Power Source to the ARDUINO ....... then to this PBC Board to hold these up to 42 Leds/Resistor, file down the top of the Led to have and glue a 0.75mm Fiber Optic that will be housed in Styrene Tube through the Layout up about 65mm above to a BLACK BACKGROUND Board with holes to hold these Fiber Optic, to OPERATE when the point changes.
This ONE NUMBER(0-9) will only be ON, one at a time.
THANK for your time

Words, words and words. Get hold of a pen and paper and show us. Some LEDs here and some LEDs there could be okey without extra power but You need to be more specific.
MUCH MORE
WOW, and here is me trying to keep the post down to a minimum, I will attempt to draw a picture
Have been given some information on a MEGA and it has got 54 Digital PINs, but 15 of them provide PWM output so I need to find about PWM.
After watching a lot of UK RAIL Videos, I have come across this, what seems to be getting bigger, but being compared with Ladder on the left, it may be over 12inches or 300mm square, anyway I may have someone kind enough to go back to where THEY took their videos and do some measuring for me.
Still waiting for some components to arrive, and it has been bought to my Attention there could be something similar to mine out there already, as far I can see these are STATIC and costly which is understandable.
I’m sorry, maybe because I’m not a model rail hobbyist, but I have almost no idea what you’re trying to make.
What is that gantry thing, I don’t see any displays there, other than the two possible lights (circles) at the right.
Running hundreds of LEDs from a single arduino is quite easy - possible even from a single I/O pin. If they’re static, you don’t even need an arduino to turn them on or off.
Dot matrix displays are commonplace, 5x7 and 8x8 matrices are ‘off the shelf’ - in 1,2 or 3 colours per LED… driving them depends on what you need to display.
PWM is one means to control the brightness of LEDs, but entirely depends on how they’re powered and connected.
HI Lastchancename,
this PICTURE shows, on the left a Safety Ladder, on the right there is 2(maybe 1, 3,4) Round lights that were up until recent times the NORM for Signals the LARGE BLACK SQUARE is the NEW VERSION of INDICATION or SIGNAL that is ahead, there is another BLACK BOARD. smaller, I am not sure what this one does, what I plan to have this bigger one, with all the (depending what Number of LEDs(6 across and6 down = 36 x0.75, (or 5x5=25))) 0.75mm Fiber Optic inside a square or oblong pole to go through the layout to a PCB Board and 3mm leds that will get instructions via a MEGA
hopefully near the HO SCALE (3.4mm=1foot) as possible, but seeing it will be MY LAYOUT I could live with a little bigger, will have to wait and see how I go in getting all THIS LITTLE STUFF together and have it WORKING with numbers that will indicate one of 10 points ahead, so that this board will show 0-9 or it might 1-0 to represent one of these points.
more later perhaps
