Beautiful work mel. By the way 84 is good. Same age and still hiking mountains.

Well I’m not doing that good, but that’s another topic.
How about doing a fairly good size post on what you have ending up with what you would like to end up with. There is a lot involved with a model railroad signaling system. Pictures would help.
Multiple lights wither LED or incandescent need to be turned on and off as well as the length of each cycle. My norm is to go berserk with overkill with everything but it has to work trouble free.
Over the years I have used all kinds of signaling systems as well as obstacle detection. My first detection was the Twin T circuit in the late 60s and believe it or not it worked the best.
Every thing went super until DCC appeared for me in 2006. Since then I tried several DCC current detection systems and wasn’t happy with any of them. DCC is temperamental at best so current detection fell out of view.
Optical works but gets quite cumbersome in the installation. I finally settled on the Arduino FC-51 for ease and cost, at 49¢ each that clinched it.
My health has dinged my working on my layout so my IR detection system isn’t complete but works good enough for me now. Where it is complete it works great, not one problem.
Here is a link to my blog optical system.

Turned 84 last July, aging is definitely not for wimps.

Hope you feel better.
I have reached my answer. I have just purchased a Logic Rail BA/2-SBCA-IR.
This will give me the ability to place two signal in different location and be able to deal with the Incandescents. As you can see it is an IR system so I don’t have to worry about light.
I appreciate all the help from all of you.

Although my Arduino circuit drives relays, the priniciple is the same. Using a transistor and resistor booster to allow the low voltage and current of the Arduino output to drive a device with higher voltage and/or current requirements. In the upper right corner of the diagram below is the “Relay Booster”. It uses 2N2222 transistors and 1 K resistors to drive the higher current relays as described in the diagram. Just substitute your incandescent lamps for the relays. The 2N2222 can drive about 600 mA at 30 volts but it’s wise to keep that well below the limits.
