Hi,
Can anyone provide a wiring diagram for using bi-colour LED's on a mimic panel to show which way a point is set?
What I'm trying to do is use the LED's show green for point set correctly and show red on the line that the point is not set for. I have the power from the track and a wire from the frog which changes to + or - depeding on the direction the point is set. I just need a wiring diagram to show how to wire it up so it works.
I've had a search and have found how to do it for 3 pin red/green LED's, but not 2 pin. And as a novice I'm struggling to work it out.
I realise you need resistors, but I'm also unsure which ones? The track is DCC using a NCE PowerCab.
Any help or a point in the right direction would be appreciated.
Cheers.
