Ok 1st set up command blocks like the picture shows don't worry about the redstone clock yet though,
but in the 1st command block (on the very left) put "/testfor @e[type=Arrow] {inGround:1b}" without the quotes. What it does is look for type arrow that's been inGround:1b or been in the ground for a tick.
            After it sucesfully finds that it will activate the comparator and activate the 2nd command block to /tp @p @e[type=Arrow]. So it will teleport the closest person (you can change @p to your minecraft username if you prefer)to the arrow that has been in the ground for one tick. 
            Then The repeater will activate and do /kill @e[type=Arrow] This kills the arrow so arrows won't be all over the world if you spam it. This is optional but I think It'd be helpful. 
and to activate it make a 2 repeater clock like that picture shows.
If you don't know how to do that place repeaters right next to each other making them face opposite directions.
Connect the corners with 4 redstone and then send 1 of the corners of redstone to connect to the 1st command block
Like the picture shows Then add a lever to another corner and flick it as fast as you can then it should make a strobe effect to show that it's working. If that's too hard another way to activate it is place a redstone torch to light the whole thing up break the torch break a piece of redstone and replace it as fast as possible.
                                              WARNING YOU'LL NEED TO PLAY IN 1.8 SNAPSHOTS FOR THIS TO WORK
and if it still doesn't work copy the commands directly from this block using control+c and control+v
