I need to create a 5 function circuit using logic gates. I need to create a circuit showing a garage door functions UP,DOWN,LOCK,UNLOCK and ERROR. I have been working on this a few days. Can't really seem to get it any help would be great. I know I was using a combination AND/OR. Then I was using a NOT for the UNLOCK/LOCK function. Just can't seem to put it all together. Thanks T
