The work team has done for the sand flow system is to simulate the motion of sand to realize the sand matrix game on PiTFT screen. The piTFT screen is hand held by users so that users are able to control the flowing direction of the sand by turning around the PiTFT screen. The final project can be divided into two parts: hardware and software. The hardware part is to realize gravity sensitivity by using the accelerometer BNO055 from Adafruit. It is used to detect the angles how much the piTFT screen has been turned and rotated. The platform used is the Raspberry pi and piTFT to display the game. For the software part, team implements all three modes which include sand flowing with barrier, nozzle and swipe to flow based on the algorithm of cellular automation. Also, the color of the sand and the specific nozzle chosen for releasing sand are controlled by the GPIO buttons on the board.
