This project was my final project for the Embedded Systems Class at John Brown University. For this project, I used a Sparkfun RGB and Gesture Sensor, an Arduino, and a Raspberry Pi. I used the Arduino to read in gesture directions from the gesture sensor and then set a certain GPIO pin high, delayed, and then set the pin low based on which direction was sensed, left or right. This GPIO pin was connected toa a GPIO pin on the Raspberry Pi. The Raspberry Pi took the signal from the GPIO pin and sent a specified command out to the Linux command line from an already running Bash script. The command sent changed the page of an open PDF file on the Raspberry Pi GUI based on the gesture direction.
