The Gatehouse

To unlock the small gate you need to click on the 5 buttons on the lock in order so that you are always following the arrows. The button you start with is the one where the arrow is leading away. Once you have unlocked the gate go through it to find a small building which will be a kitchen. Pick up the lemons and the electrical diagram which you will find in a book on the shelf and then go back outside and click on the electrical box.

Drag the lemons on to the power grid so that each of them connects a positive and negative terminal (there will be one lemon left over that you will take with you). Once you have done this climb right up on to the roof and take the hook from the far left and attach it to the antenna. Press the red flashing switch on the front of the building, then go up and sit on the antenna to complete the area.
