Hi, I purchased a DIY gamer kit from Technology will save us.
It was working fine on there computer. So I brought it home so I could program the games, and I installed all the software and libaries required on the website and when the gamer is plugged in and I upload the code I get the following error message:
error: 'Gamer' does not name a type
Help would be appriciated 
Im running the latest version of Mac OSX if that helps!
and I installed all the software and libaries required on the website
But, I have no intention of telling you which website.
Clearly you did not install some require library, or you did not install it in the right place.
Sorry, here is the link http://www.techwillsaveus.com/resources/diy-gamer-kit-arduino-library-download/
I followed the instructions excatly..
I'll try uninstalling and reinstalling it
I'll try uninstalling and reinstalling it
Don't do that, yet.
In your libraries folder, do you have directories called Gamer and Tone, or do you have a directory called Gamer-master? You should have Gamer and Tone. If you have Gamer-master, move the contents to the libraries folder, and delete Gamer-master.
You did restart the IDE after installing the libraries, right?
