I would like help with a door lock system and a knight rider sketch also

That's great   robotBuilder thanks but I need the water sensor also since I need all of this to work like this type of thing to display on the OLED screen example ( C. 21 H. 51%                                                                                                                                         W. L, M, or H) 

and since I am so new at this well I am having problem's all over the place so I can test the acid in the tomato's that are ether grown from the ground or in a hydroponique bay and that goes the same for other veg's too, also to find out what grow's better to make some bigger and will they be in a way more healthy then store bought or home grown, See where I am trying to go with this? 😛
