Hello Everyone,
I'm new to electronics and arduino. I want some help from some of you. I want to build a drum kit with an arduino and I want 12 inputs. How to make it and what should I use,two arduinos or arduino mega? Please give me some step by step info to make one. I hope you all will help me.
Thanks. 
I'm assuming that you want to play audio samples when you hit each drum ?
So you'll need to interface to the sound generation device as well as the inputs from the pads.
You can easily do 12 inputs, A0 to A6 gives 6 inputs, D2 to D8 will give you another 6, i.e 12 in total
Leaving D9 upwards to use for the sound creation control e.g. via SPI, or were you intending to drive a mini device?

I think all Arduinos have 12 inputs...
Please do not cross-post. Other thread removed.
and I want 12 inputs.
I think the point some people are making is assuming you want digital inputs. That will only record a hit or no hit. Do you need to know how hard you have hit something? In which case you will need 12 analogue inputs. While there are ways of making a Uno do this, it is much simpler with a Mega as you can have 12 analogue inputs straight off on that.
Please give me some step by step info to make one.
Sorry but that is not what we do here. We are not a code writing service not a project generation service.
What we do is help you learn and help you correct any errors you might make.

Well there are lots of shields for this
e.g.
Or if you have a Due
