Hey guys, sorry if this has been asked before, I did searches but couldn't find any thing that remotely covers what I would like to do. I have limited electronics knowledge
http://www.kpsec.freeuk.com/projects/trafficlight.htm
The above link refers to a traffic light simulator that runs off a 9v PP3 battery, I would like to use a 12v SLA battery which has a nominal output voltage of 13.8v, but I doubt I can just connect it up?
So what would I need to add or change to allow this to occur?
I assume just a greater resistor?
