learn to use red stone dust, i've been toying with AND gates and i have made a door which is hidden behind a painting (you can walk through paintings, place em then destroy the blocks behind em) and two hidden levers that are burried around my house and once both are activated it lets you in.
How do I go about setting up levers and switches? I don't really get how you make them do anything specific...
well, levers, buttons and preasure pads can open and close doors, blow up TNT and switch mine cart tracks. when a switch is hit is is set to on or off, and stays that way till it is hit again, buttons are off until hit, then they are on for 1 second before turning off again. preasure pads come in wood and stone, they are active as long as something is on them. wood pads can be activated by anything on them (you, mobs, dropped objects and minecarts) while stone can only be activated by you, mobs or a minecart with someone in it.
when on or off they only affect anything in the adjecent square or 2 squares below it, but if you put red stone dust there it will act as a wire, moving the current up to 15 blocks away from its power source.
it can take a while to learn but once you get better you can add reapeters (they add another 15 blocks to the range each), inverters that take an on current and turn it off and vice versa, and logic gates (AND gates, OR gates etc).
i advise you read all of this

that explains it, aswell as look at some youtube videos (almatybob has some good ones).
