I don't have any idea what range of output you are getting from your velostat sensor. You need to test it to see what values you get with a projectile impact and filter everything else.

Right now is like 282 since I readjusted it.And than when I press it , it goes up and than goes down to 279 and than back to 281.So I don't think this is very accurate at all.I think right now I want to know if that accelrometer you were talking about is arduino connectable and is compatible for bread board pins.

All of our accelerometers are compatible with Arduinos. And there are links to the tutorials on the product page. Here is the tutorial for the LIS3DH.

Since this is on a wearable device, you will want something that is flexible. So I would use a small gauge stranded wire. Something in the 24 to 30 AWG range.

The Metro Mini 328 is an Arduino UNO compatible board in a nice small size: https://www.adafruit.com/product/2590

I also want to connect battery to it.So I am thinking of using one of those battery cases with wires so I can solder them.This one I am looking at is like the first thing that shows up when I search "9v battery case" on Amazon.Here is the link to what I am looking at.

https://www.amazon.com/LAMPVPATH-Pack-B ... ics&sr=1-3

Will I be able to solder the wires from the battery case, if not what is another way how to do this?

9v is way more than you need. A 4xAA is a better choice: https://www.adafruit.com/product/830

An even better option would be a Feather 32U4 : https://www.adafruit.com/product/2771

This will run from a 3.7V LiPo and has a built-in charger.

Well I am connecting 1 servo motor,1 lcd, and like 50 sensors to it, so I think I need a good amount of voltage.So will that chargeable feather support enough voltage for that?And are the wires from a battery case solderable?
