What can I destroy with my arrows?

Question

I want to build an archery range in Minecraft. I want to have targets pop up in different places like an FPS tutorial. I need some way to detect whether the arrows hit the targets or not.

What can I change by the impact of an arrow?

Answer

The extent to which arrows can affect Redstone circuits is covered on the wiki.

While arrows shot at Switches or Pressure Plates will not trigger said inputs directly (unless fired from a dispenser onto a pressure plate), workarounds can be used to trigger circuits from a distance. For instance, a minecart can be used in such a way that destroying it with arrows releases the wooden pressure plate it is resting on, or a painting can be shot off a wall and fall onto a wooden pressure plate to activate it. As of 1.8 and the increase of arrow damage, boats can be used as targets since a fully charged bow will break the boat in one shot.

For your range, I'd suggest making it out of boats and paintings. These will break when arrows hit them and turn into items, which can then fall and trigger pressure plates.
