Hi Paul
The reason you might not understand is because my work might be completely wrong. i'm not sure of the correct way to use the transistors for what i need them to do.
I have made a working timer circuit with code that works. that is all fine. all I am having trouble with is now making that same peace of hardware work with a Higher voltage display
so instead of these display's a small single LED. I need a high powered LED strip
something i was looking at using are CMOS devices
is that something i could use to just switch the single from my Arduino to trigger and 24v system then back of again?
Thanks
