How to spawn Dropped Items!

Have you ever had the frustration on spawning item entities? or maybe you just don't know how?
Well you too can do this also!
All you need is a command block and a button and we can get crack'alackin!
First Type in this: ;
/summon Item X Y Z
Now Item is the entity id for dropped items.
In replace of the X Y Z are the coordinates where it is gonna be spawned in.

Next:add in this tag:
{Item:{id:#,Damage:#,Count:#}}
Inside the #s you need to put in your value of each specific tag.
id = the item id of the item you want to spawn
Damage = the value of it either being damaged or has counterparts of its self.
(Note:Item Damage refers to Equipment and Tool, as for Damage Data Value refers to counterparts of the item you are spawning.
e.g.A mob head has 5 counterparts so you need to use the Damage Value into either 2,3,4 or 5 to get the respective mob head you want.)

Now that you have input all of the commands together it should look like this:
/summon Item X Y Z {Item:{id:#,Damage:#,Count:#}}

again just input you values to their respective places.

now put the button on and activate and it should work!

One thing:you can also add in some extra tags like custom names,attributes and etc., but you have to figure that on your own!

If you can't i'll do a later tutorial for this kind of spawning.
