Using the Bumper Switches

Hi

Im new to robotics and therefore I’m looking for some parts for my first robot. I’m looking at the Bumper Switch Assembly Kit ( lynxmotion.com/p-60-bumper-s … y-kit.aspx ). Before i buy i just want to know how hard it is to use the bumper switches with an Arduino? How many pins does the switches require and which pins?

Thanks! :slight_smile:
