    I need someone to help me with a project that I am working on which involves an arduino that is connected to 6 push buttons as inputs and 6 motors as outputs. The theory is pretty simple, when one presses a particular button it should trigger a certain - or several - motors to be on for a short amount of time, and then turn off. I can give more details to whomever takes this up.
