Arduino as a HMI for S7-200

For an integration project I made  for a class I built  a System that controls a motor using A Siemens S7-200 PLC that is controlled by an Arduino UNO as a controller and HMI and made a manual on how each part works. This Project was chosen to be displayed at the schools open house in November 2014.

Here’s the manual and a video of it in operation. Please excuse the crudity of the system and video I am limited to the equipment the school has.
