Let me describe this in a little more detail:
1) this is for a cell matching game.
2) On the console, is a list of cell parts
3) On the top is a diagram of a cell
4) The player touches a lead to a name and another lead to a metal post on the image of the cell that correspond to the part
5) I only have two leds, one green and one red.
I need to build a logic circuit. The following is a simple illustration (a o represents a metal post) followed by the logic table:
o A o 1
o B o 2
o C o 3
I want the green light to illuminate if the post at A and the post at 1 are touched, i.e.,
A and 1, or
B and 2, or
C and 3
I want the red light to illuminate if the post at B and either post 2 or 3 are touched:
A and (2or3), or
B and (1or3), or
C and (1or2)
If this can be build using simple circuits that would be great; however, I have almost decided that some ttl logic will be required.
