This design is a doorbell for your house. You will need a 2 x 4 x 4 area.
== Basic Design ==
# Find where you want your button. It has to be on the bottom block of the wall to the right of the door.
# Dig down one block below the button.
# Place redstone dust in the hole.
# Dig down two blocks on the side of the hole farthest from the door.
# Place redstone dust in the hole.
# Dig out a 3×3 hole that is 2 blocks deep in front of the two existing holes.
# Place redstone dust on the farthest and nearest blocks to the right.
# Place a redstone repeater between the redstone dust at four ticks delay.
# Dig down one block to the left of each piece of redstone dust.
# Place a block of choice in what you just dug (sets instrument for note blocks).
# Place a note block on top of each block of choice.
# Set the tone for the two note blocks.
# Replace the top layer (ground level) of the hole with a natural block.
# Place your button.
You are done!
== Redstone Tips ==
* Use blocks of gold for the block of your choice under the note blocks to get a bell sound, which sounds similar to a real doorbell
* Right-click the first note block 6 times, and the second one 2 times, to create doorbell-like pitches.
* You can use a pressure plate instead of a button, for an automatic doorbell.
