Hello,

I have completed my truth table, boolean expression, logic diagram and wired up everything, but I do not know what's wrong with my logic gate. I've checked over my wiring and everything but the outputs do not correspond to my truth table.

Logic diagram: imgur: the simple image sharer (http://imgur.com/tkWk5wM)

Truth Table: http://imgur.com/KGKH27j

Boolean Expression: (A+B)(B+C)

Breadboard: imgur: the simple image sharer (http://imgur.com/tDbJP0t)

Gates from left to right: OR, AND, NOT

Red wire is input A
Purple/blue is input B
White is input C

I do not know why it is not working according to my truth table. Is my truth table the problem?

Thanks
