I am trying to build three circuits, an AND, a OR and a NOT gate for a personal side project.
I think I have the logic part down right, i.e. using the following gate logic:
I'm building this by connecting two switches and a led to a 4011 Integrated Circuit. I'm powering this with an Arduino (5V) or battery (6V).
Here is the newbie question. The behavior of the IC is ...inconsistent once I try to cross connect any pins In order to use more than one gate (e.g. to build the AND gate)
What resistors do I need to insert in this circuit to make it work properly? How do I calculate their value? Or is it simply a case that I can't use the IC like this?
