Hello All,
I need alittle help with a project circuit....

I have two microswitches NO/NC that show the position of 2 latches on a Hatch..

What I want to do is Show the hatch open RED BiPolar LED all the time, no matter if one of the switches is closed (latched). When both switches are closed (latched) show the Green BiPolar.

Any Ideas how to draw this, or make it work?

 

Have you read this?

LEDs, 555s, Flashers, and Light Chasers

Chapter 4 - The 555 Integrated Circuit

It covers some of what you are asking.

 

thanks, im reading it right now.
