This note shows a sample how to I/O programming of RaspberryPi with Mathematica. Mathematica I/O is not so fast comparing Python etc. however, we can find many strong points through the projects. This sample project shows following I/O programming example.
 
 
 - I2C connected SSD1306-OLE display module handling
  
 - SG90 servo motor driving method through GPIO pin
  
 - GPIO shutdown switch setup
  

You can see the movie here.
